Prior risk assessment etc. 7 1 Before a radiation employer commences a new activity involving work with ionising radiation in respect of which no risk assessment has been made by him, he shall make a suitable and sufficient assessment of the risk to any employee and other person for the purpose of identifying the measures he needs to take to restrict the exposure of that employee or other person to ionising radiation. 2 Without prejudice to paragraph (1), a radiation employer shall not carry out work with ionising radiation unless he has made an assessment sufficient to demonstrate that— a all hazards with the potential to cause a radiation accident have been identified; and b the nature and magnitude of the risks to employees and other persons arising from those hazards have been evaluated. 3 Where the assessment made for the purposes of this regulation shows that a radiation risk to employees or other persons exists from an identifiable radiation accident, the radiation employer shall take all reasonably practicable steps to— a prevent any such accident; b limit the consequences of any such accident which does occur; and c provide employees with the information, instruction and training, and with the equipment necessary, to restrict their exposure to ionising radiation. 4 The requirements of this regulation are without prejudice to the requirements of regulation 3 (Risk assessment) of the Management of Health and Safety at Work Regulations (Northern Ireland) 1992 . Restriction of exposure 8 1 Every radiation employer shall, in relation to any work with ionising radiation that he undertakes, take all necessary steps to restrict so far as reasonably practicable the extent to which his employees and other persons are exposed to ionising radiation. 2 Without prejudice to the generality of paragraph (1), a radiation employer shall— a so far as reasonably practicable achieve the restriction of exposure to ionising radiation required under that paragraph by means of engineering controls and design features and in addition by the provision and use of safety features and warning devices; and b in addition to sub-paragraph ( a ), provide such systems of work as will, so far as is reasonably practicable, restrict the exposure to ionising radiation of employees and other persons; and c in addition to sub-paragraphs ( a ) and ( b ), where it is reasonably practicable to further restrict exposure to ionising radiation by means of personal protective equipment, provide employees or other persons with adequate and suitable personal protective equipment (including respiratory protective equipment) unless the use of personal protective equipment of a particular kind is not appropriate having regard to the nature of the work or the circumstances of the particular case. 3 Where it is appropriate to do so at the planning stage of radiation protection, dose constraints shall be used in restricting exposure to ionising radiation pursuant to paragraph (1). 4 An employer who provides any system of work or personal protective equipment pursuant to this regulation shall take all reasonable steps to ensure that it is properly used or applied as the case may be. 5 Without prejudice to paragraph (1), a radiation employer shall ensure that— a in relation to an employee who is pregnant, the conditions of exposure are such that, after her employer has been notified of the pregnancy, the equivalent dose to the foetus is unlikely to exceed 1 mSv during the remainder of the pregnancy; and b in relation to an employee who is breastfeeding, the conditions of exposure are restricted so as to prevent significant bodily contamination of that employee. 6 Nothing in paragraph (5) shall require the radiation employer to take any action in relation to an employee until she has notified her employer in writing that she is pregnant or breastfeeding and the radiation employer has been made aware, or should reasonably have been expected to be aware, of that fact. 7 Every employer shall, for the purpose of determining whether the requirements of paragraph (1) are being met, ensure that an investigation is carried out forthwith when the effective dose of ionising radiation received by any of his employees for the first time in any calendar year exceeds 15m Sv or such other lower effective dose as the employer may specify, which dose shall be specified in writing in local rules made pursuant to regulation 17(1) or, where local rules are not required, by other suitable means. Personal protective equipment 9 1 Any personal protective equipment provided by an employer pursuant to regulation 8 shall comply with any provision in the Personal Protective Equipment ( EC Directive) Regulations 1992 which is applicable to that item of personal protective equipment. 2 Where in the case of respiratory protective equipment no provision of the Regulations referred to in paragraph (1) applies, that respiratory protective equipment shall satisfy the requirements of regulation 8 only if it is of a type, or conforms to a standard, approved in either case— a by the Executive; or b by the Great Britain Executive under regulation 9(2) of the Great Britain Regulations. 3 Every radiation employer shall ensure that appropriate accommodation is provided for personal protective equipment when it is not being worn. Maintenance and examination of engineering controls etc. and personal protective equipment 10 1 A radiation employer who provides any engineering control, design feature, safety feature or warning device to meet the requirements of regulation 8(2)( a ) shall ensure— a that any such control, feature or device is properly maintained; and b where appropriate, that thorough examinations and tests of such controls, features or devices are carried out at suitable intervals. 2 Every radiation employer shall ensure that all personal protective equipment provided pursuant to regulation 8 is, where appropriate, thoroughly examined at suitable intervals and is properly maintained and that, in the case of respiratory protective equipment, a suitable record of that examination is made and kept for at least two years from the date on which the examination was made and that the record includes a statement of the condition of the equipment at the time of the examination. Dose limitation 11 1 Subject to paragraph (2) and to paragraph 5 of Schedule 4, every employer shall ensure that his employees and other persons within a class specified in Schedule 4 are not exposed to ionising radiation to an extent that any dose limit specified in Part I of that Schedule for such class of person is exceeded in any calendar year. 2 Where an employer is able to demonstrate in respect of any employee that the dose limit specified in paragraph 1 of Part I of Schedule 4 is impracticable having regard to the nature of the work undertaken by that employee, the employer may in respect of that employee apply the dose limits set out in paragraphs 9 to 11 of that Schedule and in such case the provisions of Part II of the Schedule shall have effect. Contingency plans 12 1 Where the assessment made in accordance with regulation 7 shows that a radiation accident is reasonably foreseeable (having regard to the steps taken by the radiation employer under paragraph (3) of that regulation), the radiation employer shall prepare a contingency plan designed to secure, so far as is reasonably practicable, the restriction of exposure to ionising radiation and the health and safety of persons who may be affected by such accident. 2 The radiation employer shall ensure that— a where local rules are required for the purposes of regulation 17, a copy of the contingency plan made in pursuance of paragraph (1) is identified in those rules and incorporated into them by way of summary or reference; b any employee under his control who may be involved with or may be affected by arrangements in the plan has been given suitable and sufficient instructions and where appropriate issued with suitable dosemeters or other devices obtained in either case from the approved dosimetry service with which the radiation employer has entered into an arrangement under regulation 21; and c where appropriate, rehearsals of the arrangements in the plan are carried out at suitable intervals. Part III Arrangements for the Management of Radiation Protection Radiation protection adviser 13 1 Subject to paragraph (3), every radiation employer shall consult such suitable radiation protection advisers as are necessary for the purpose of advising the radiation employer as to the observance of these Regulations and shall, in any event, consult one or more radiation protection advisers with regard to those matters which are set out in Schedule 5. 2 Where a radiation protection adviser is consulted pursuant to the requirements of paragraph (1) (other than in respect of the observance of that paragraph), the radiation employer shall appoint that radiation protection adviser in writing and shall include in that appointment the scope of the advice which the radiation protection adviser is required to give. 3 Nothing in paragraph (1) shall require a radiation employer to consult a radiation protection adviser where the only work with ionising radiation undertaken by that employer is work specified in Schedule 1. 4 The radiation employer shall provide any radiation protection adviser appointed by him with adequate information and facilities for the performance of his functions. Information, instruction and training 14 Every employer shall ensure that— a those of his employees who are engaged in work with ionising radiation are given appropriate training in the field of radiation protection and receive such information and instruction as is suitable and sufficient for them to know— i the risks to health created by exposure to ionising radiation; ii the precautions which should be taken; and iii the importance of complying with the medical, technical and administrative requirements of these Regulations; b adequate information is given to other persons who are directly concerned with the work with ionising radiation carried on by the employer to ensure their health and safety so far as is reasonably practicable; and c those female employees of that employer who are engaged in work with ionising radiation are informed of the possible risk arising from ionising radiation to the foetus and to a nursing infant and of the importance of those employees informing the employer in writing as soon as possible— i after becoming aware of their pregnancy; or ii if they are breast feeding. Co-operation between employers 15 Where work with ionising radiation undertaken by one employer is likely to give rise to the exposure to ionising radiation of the employee of another employer, the employers concerned shall co-operate by the exchange of information or otherwise to the extent necessary to ensure that each such employer is enabled to comply with the requirements of these Regulations in so far as his ability to comply depends upon such co-operation. Part IV Designated Areas Designation of controlled or supervised areas 16 1 Every employer shall designate as a controlled area any area under his control which has been identified by an assessment made by him (whether pursuant to regulation 7 or otherwise) as an area in which— a it is necessary for any person who enters or works in the area to follow special procedures designed to restrict significant exposure to ionising radiation in that area or prevent or limit the probability and magnitude of radiation accidents or their effects; or b any person working in the area is likely to receive an effective dose greater that 6mSv a year or an equivalent dose greater than three-tenths of any relevant dose limit referred to in Schedule 4 in respect of an employee aged 18 years or above. 2 An employer shall not intentionally create in any area conditions which would require that area to be designated as a controlled area unless that area is for the time being under the control of that employer. 3 An employer shall designate as a supervised area any area under his control, not being an area designated as a controlled area— a where it is necessary to keep the conditions of the area under review to determine whether the area should be designated as a controlled area; or b in which any person is likely to receive an effective dose greater than 1mSv a year or an equivalent dose greater than one-tenth of any relevant dose limit referred to in Schedule 4 in respect of an employee aged 18 years or above. Local rules and radiation protection supervisors 17 1 For the purposes of enabling work with ionising radiation to be carried on in accordance with the requirements of these Regulations, every radiation employer shall, in respect of any controlled area or, where appropriate having regard to the nature of the work carried out there, any supervised area, make and set down in writing such local rules as are appropriate to the radiation risk and the nature of the operations undertaken in that area. 2 The radiation employer shall take all reasonable steps to ensure that any local rules made pursuant to paragraph (1) and which are relevant to the work being carried out are observed. 3 The radiation employer shall ensure that such of those rules made pursuant to paragraph (1) as are relevant are brought to the attention of those employees and other persons who may be affected by them. 4 The radiation employer shall— a appoint one or more suitable radiation protection supervisors for the purpose of securing compliance with these Regulations in respect of work carried out in any area made subject to local rules pursuant to paragraph (1); and b set down in the local rules the names of such individuals so appointed. Additional requirements for designated areas 18 1 Every employer who designates any area as a controlled or supervised area shall ensure that any such designated area is adequately described in local rules and that— a in the case of any controlled area— i the area is physically demarcated or, where this is not reasonably practicable, delineated by some other suitable means; and ii suitable and sufficient signs are displayed in suitable positions indicating that the area is a controlled area, the nature of the radiation sources in that area and the risks arising from such sources; and b in the case of any supervised area, suitable and sufficient signs giving warning of the supervised area are displayed, where appropriate, in suitable positions indicating the nature of the radiation sources and the risks arising from such sources. 2 The employer who has designated an area as a controlled area shall not permit any employee or other person to enter or remain in such an area unless that employee or other person— a being a person other than an outside worker, is a classified person; b being an outside worker, is a classified person in respect of whom the employer has taken all reasonable steps to ensure that the person— i is subject to individual dose assessment pursuant to regulation 21; ii has been provided with and has been trained to use any personal protective equipment that may be necessary pursuant to regulation 8(2)( c ); iii has received any specific training required pursuant to regulation 14; and iv has been certified fit for the work with ionising radiation which he is to carry out pursuant to regulation 24; or c not being a classified person, enters or remains in the area in accordance with suitable written arrangements for the purpose of ensuring that— i in the case of an employee aged 18 years or over, he does not receive in any calendar year a cumulative dose of ionising radiation which would require that employee to be designated as a classified person; or ii in the case of any other person, he does not receive in any calendar year a dose of ionising radiation exceeding any relevant dose limit. 3 An employer who has designated an area as a controlled area shall not permit a person to enter or remain in such area in accordance with the written arrangements under paragraph (2)( c ), unless he can demonstrate, by personal dose monitoring or other suitable measurements, that the doses are restricted in accordance with that paragraph. 4 An employer who has designated an area as a controlled area shall, in relation to an outside worker, ensure that— a the outside worker is subject to arrangements for estimating the dose of ionising radiation he receives whilst in the controlled area; and b as soon as is reasonably practicable after the services carried out by that outside worker in that controlled area are completed, an estimate of the dose received by that worker is entered into his radiation passbook; and c when the radiation passbook of the outside worker is in the possession of that employer, the passbook is made available to that worker upon request. 5 The employer who carries out the monitoring or measurements pursuant to paragraph (3) shall keep the results of the monitoring or measurements referred to in that paragraph for a period of 2 years from the date they were recorded and shall, at the request of the person to whom the monitoring or measurements relate and on reasonable notice being given make the results available to that person. 6 In any case where there is a significant risk of the spread of radioactive contamination from a controlled area, the employer who has designated that area as a controlled area shall make adequate arrangements to restrict, so far as is reasonably practicable, the spread of such contamination. 7 Without prejudice to the generality of paragraph (6), the arrangements required by that paragraph shall, where appropriate, include— a the provision of suitable and sufficient washing and changing facilities for persons who enter or leave any controlled or supervised area; b the proper maintenance of such washing and changing facilities; c the prohibition of eating, drinking or smoking or similar activity likely to result in the ingestion of a radioactive substance by any employee in a controlled area; and d the means for monitoring for contamination any person, article or goods leaving a controlled area. Monitoring of designated areas 19 1 Every employer who designates an area as a controlled or supervised area shall take such steps as are necessary (otherwise than by use of assessed doses of individuals), having regard to the nature and extent of the risks resulting from exposure to ionising radiation, to ensure that levels of ionising radiation are adequately monitored for each such area and that working conditions in those areas are kept under review. 2 The employer upon whom a duty is imposed by paragraph (1) shall provide suitable and sufficient equipment for carrying out the monitoring required by that paragraph, which equipment shall— a be properly maintained so that it remains fit for the purpose for which it was intended; b be adequately tested and examined at appropriate intervals. 3 Equipment provided pursuant to paragraph (2) shall not be or remain suitable unless— a the performance of the equipment has been established by adequate tests before it has first been used; and b the tests and examinations carried out pursuant to paragraph (2) and sub-paragraph ( a ) have been carried out by or under the supervision of a qualified person. 4 The employer upon whom a duty is imposed by paragraph (1) shall— a make suitable records of the results of the monitoring carried out in accordance with paragraph (1) and of the tests carried out in accordance with paragraphs (2) and (3); b ensure that the records of the tests carried out pursuant to sub-paragraph ( a ) are authorised by a qualified person; and c keep the records referred to in sub-paragraph ( a ), or copies thereof, for at least 2 years from the respective dates on which they were made. Part V Classification and Monitoring of Persons Designation of classified persons 20 1 Subject to paragraph (2), the employer shall designate as classified persons those of his employees who are likely to receive an effective dose in excess of 6mSv per year or an equivalent dose which exceeds three-tenths of any relevant dose limit and shall forthwith inform those employees that they have been so designated. 2 The employer shall not designate an employee as a classified person unless— a that employee is aged 18 years or over; and b an appointed doctor or employment medical adviser has certified in the health record that that employee is fit for the work with ionising radiation which he is to carry out. 3 The employer may cease to treat an employee as a classified person only at the end of a calendar year except where— a an appointed doctor or employment medical adviser so requires; or b the employee is no longer employed by the same employer in a capacity which is likely to result in significant exposure to ionising radiation during the remainder of the relevant calendar year. Dose assessment and recording 21 1 Every employer shall ensure that— a in respect of each of his employees who is designated as a classified person, an assessment is made of all doses of ionising radiation received by such employee which are likely to be significant; and b such assessments are recorded. 2 For the purposes of paragraph (1), the employer shall make suitable arrangements with one or more approved dosimetry service for— a the making of systematic assessments of such doses by the use of suitable individual measurement for appropriate periods or, where individual measurement is inappropriate, by means of other suitable measurements; and b the making and maintenance of dose records relating to each classified person. 3 For the purposes of paragraph (2)( b ), the arrangements that the employer makes with the approved dosimetry service shall include requirements for that service— a to keep the records made and maintained pursuant to the arrangements or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from when they were made; b to provide the employer at appropriate intervals with suitable summaries of the dose records maintained in accordance with sub-paragraph ( a ); c when required by the employer, to provide him with such copies of the dose record relating to any of his employees as the employer may require; d when required by the employer, to make a record of the information concerning the dose assessment relating to a classified person who ceases to be an employee of the employer, and to send that record to the Executive and a copy thereof to the employer forthwith, and a record so made is referred to in this regulation as a “termination record”; e within 3 months, or such longer period as the Executive may agree, of the end of each calendar year to send to the Executive summaries of all current dose records relating to that year; f when required by the Executive, to provide it with copies of any dose records; g where a dose is estimated pursuant to regulation 22, to make an entry in a dose record and retain the summary of the information used to estimate that dose; h where the employer employs an outside worker, to provide, where appropriate, a current radiation passbook in respect of that outside worker; and i where the employer employs an outside worker who works in Great Britain or another member State, to maintain a continuing record of the assessment of the dose received by that outside worker when working in such place. 4 The employer shall provide the approved dosimetry service with such information concerning his employees as is necessary for the approved dosimetry service to comply with the arrangements made for the purposes of paragraph (2). 5 An employer shall— a ensure that each outside worker employed by him is provided with a current individual radiation passbook which shall not be transferable to any other worker and in which shall be entered the particulars set out in Schedule 6; and b make suitable arrangements to ensure that the particulars entered in the radiation passbook are kept up-to-date during the continuance of the employment of the outside worker by that employer. 6 The employer shall— a at the request of a classified person employed by him (or of a person formerly employed by him as a classified person) and on reasonable notice being given, obtain (where necessary) from the approved dosimetry service and make available to that person— i a copy of the dose summary provided for the purpose of paragraph (3)( b ) relating to that person and made within a period of 2 years preceding the request; ii a copy of the dose record of that person; and b when a classified person ceases to be employed by the employer, take all reasonable steps to provide to that person a copy of his termination record. 7 The employer shall keep a copy of the summary of the dose record received from the approved dosimetry service for at least 2 years from the end of the calendar year to which the summary relates. Estimated doses and special entries 22 1 Where a dosemeter or other device is used to make any individual measurement under regulation 21(2) and that dosemeter or device is lost, damaged or destroyed or it is not practicable to assess the dose received by a classified person over any period, the employer shall make an adequate investigation of the circumstances of the case with a view to estimating the dose received by that person during that period and either— a in a case where there is adequate information to estimate the dose received by that person, shall send to the approved dosimetry service an adequate summary of the information used to estimate that dose and shall arrange for the approved dosimetry service to enter the estimated dose in the dose record of that person; or b in a case where there is inadequate information to estimate the dose received by the classified person, shall arrange for the approved dosimetry service to enter a notional dose in the dose record of that person which shall be the proportion of the total annual dose limit for the relevant period, and in either case the employer shall take reasonable steps to inform the classified person of that entry and arrange for the approved dosimetry service to identify the entry in the dose record as an estimated dose or a notional dose as the case may be. 2 The employer shall, at the request of the classified person (or a person formerly employed by that employer as a classified person) to whom the investigation made under paragraph (1) relates and on reasonable notice being given, make available to that person a copy of the summary sent to the approved dosimetry service under sub-paragraph ( a ) of paragraph (1). 3 Subject to paragraphs (5) and (8), where an employer has reasonable cause to believe that the dose received by a classified person is much greater or much less than that shown in the relevant entry of the dose record, he shall make an adequate investigation of the circumstances of the exposure of that person to ionising radiation and, if that investigation confirms his belief, the employer shall, where there is adequate information to estimate the dose received by the employee— a send to the approved dosimetry service an adequate summary of the information used to estimate that dose; b arrange for the approved dosimetry service to enter that estimated dose in the dose record of that person and for the approved dosimetry service to identify the estimated dose in the dose record as a special entry; and c notify the classified person accordingly. 4 The employer shall make a report of any investigation carried out under paragraph (3) and shall preserve a copy of that report for a period of 2 years from the date it was made. 5 Paragraph (3) shall not apply— a in respect of a classified person subject only to an annual dose limit, more than 12 months after the original entry was made in the record; and b in any other case, more than 5 years after the original entry was made in the record. 6 Where a classified person is aggrieved by a decision to replace a recorded dose by an estimated dose pursuant to paragraph (3) he may, by an application in writing to the Executive made within 3 months of the date on which he was notified of the decision, apply for that decision to be reviewed. 7 Where the Executive concludes (whether as a result of a review carried out pursuant to paragraph (6) or otherwise) that— a there is reasonable cause to believe the investigation carried out pursuant to paragraph (3) was inadequate; or b a reasonable estimated dose has not been established, the employer shall, if so directed by the Executive, re-instate the original entry in the dose record. 8 The employer shall not, without the consent of the Executive, require the approved dosimetry service to enter an estimated dose in the dose record in any case where— b the cumulative recorded effective dose is 20mSv or more in one calendar year; or b the cumulative recorded equivalent dose for the calendar year exceeds a relevant dose limit. Dosimetry for accidents etc. 23 1 Where any accident or other occurrence takes place which is likely to result in a person receiving an effective dose of ionising radiation exceeding 6mSv or an equivalent dose greater than three-tenths of any relevant dose limit, the employer shall— a in the case of a classified person, arrange for a dose assessment to be made by the approved dosimetry service forthwith; b in the case of an employee to whom a dosemeter or other device has been issued in accordance with regulation 12(2), arrange for that dosemeter or device to be examined and for the dose received to be assessed by the approved dosimetry service as soon as possible; c in any other case, arrange for the dose to be assessed by an appropriate means as soon as possible, having regard to the advice of the radiation protection adviser. 2 In such a case, the employer shall— a take all reasonably practicable steps to inform each person for whom a dose assessment has been made of the result of that assessment; and b keep a record of the assessment or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date of the relevant accident. Medical surveillance 24 1 This regulation shall apply in relation to— a classified persons and persons whom an employer intends to designate as classified persons; b employees who have received an overexposure and are not classified persons; c employees who are engaged in work with ionising radiation subject to conditions imposed by an appointed doctor or employment medical adviser under paragraph (6). 2 The employer shall ensure that each of his employees to whom this regulation relates is under adequate medical surveillance by an appointed doctor or employment medical adviser for the purpose of determining the fitness of each employee for the work with ionising radiation which he is to carry out. 3 The employer shall ensure that a health record, containing the particulars referred to in Schedule 7, in respect of each of his employees to whom this regulation relates is made and maintained and that that record or a copy thereof is kept until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date of the last entry made in it. 4 Subject to paragraph (5), the employer shall ensure that there is a valid entry in the health record of each of his employees to whom this regulation relates (other than employees who have received an overexposure and who are not classified persons) made by an appointed doctor or employment medical adviser and an entry in the health record shall be valid— a for 12 months from the date it was made or treated as made by virtue of paragraph (5); or b for such shorter period as is specified in the entry by the appointed doctor or employment medical adviser; or c until cancelled by an appointed doctor or employment medical adviser by a further entry in the record. 5 For the purposes of paragraph (4)( a ), a further entry in the health record of the same employee shall, where made not less than 11 months nor more than 13 months after the start of the current period of validity, be treated as if made at the end of that period. 6 Where the appointed doctor or employment medical adviser has certified in the health record of an employee to whom this regulation relates that in his professional opinion that employee should not be engaged in work with ionising radiation or that he should only be so engaged under conditions he has specified in the health record, the employer shall not permit that employee to be engaged in the work with ionising radiation except in accordance with the conditions, if any, so specified. 7 Where, for the purpose of carrying out his functions under these Regulations, an appointed doctor or employment medical adviser requires to inspect any workplace, the employer shall permit him to do so. 8 The employer shall make available to the appointed doctor or employment medical adviser the summary of the dose record kept by the employer pursuant to regulation 21(7) and such other records kept for the purposes of these Regulations as the appointed doctor or employment medical adviser may reasonably require. 9 Where an employee is aggrieved by a decision recorded in the health record by an appointed doctor or employment medical adviser he may, by an application in writing to the Executive made within 3 months of the date on which he was notified of the decision, apply for that decision to be reviewed in accordance with a procedure approved for the purposes of this paragraph by the Executive, and the result of that review shall be notified to the employee and entered in his health record in accordance with the approved procedure. Investigation and notification of overexposure 25 1 Where a radiation employer suspects or has been informed that any person is likely to have received an overexposure as a result of work carried out by that employer, that employer shall make an immediate investigation to determine whether there are circumstances which show beyond reasonable doubt that no overexposure could have occurred and, unless this is shown, the radiation employer shall— a as soon as practicable notify the suspected overexposure to— i the Executive; ii in the case of an employee of some other employer, that other employer; and iii in the case of his own employee, the appointed doctor or employment medical adviser; b as soon as practicable take reasonable steps to notify the suspected overexposure to the person affected; and c make or arrange for such investigation of the circumstances of the exposure and an assessment of any relevant dose received as is necessary to determine, so far as is reasonably practicable, the measures, if any, required to be taken to prevent a recurrence of such overexposure and shall forthwith notify the results of that investigation and assessment to the persons and authorities mentioned in sub-paragraph ( a ) and shall— i in the case of his employee, forthwith notify that employee of the results of the investigation and assessment, or ii in the case of a person who is not his employee, where the investigation has shown that that person has received an overexposure, take all reasonable steps to notify him of his overexposure. 2 A radiation employer who makes any investigation pursuant to paragraph (1) shall make a report of that investigation and shall— a in respect of an immediate investigation, keep that report or a copy thereof for at least 2 years from the date on which it was made; and b in respect of an investigation made pursuant to sub-paragraph ( c ) of paragraph (1), keep that report or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date on which it was made. 3 Where the person who received the overexposure is an employee who has a dose record, his employer shall arrange for the assessment of the dose received to be entered into that dose record. Dose limitation for overexposed employees 26 1 Without prejudice to other requirements of these Regulations and in particular regulation 24(6), where an employee has been subjected to an overexposure paragraph (2) shall apply in relation to the employment of that employee on work with ionising radiation during the remainder of the dose limitation period commencing at the end of the personal dose assessment period in which he was subjected to the overexposure. 2 The employer shall ensure that an employee to whom this regulation relates does not, during the remainder of the dose limitation period, receive a dose of ionising radiation greater than that proportion of any dose limit which is equal to the proportion that the remaining part of the dose limitation period bears to the whole of that period. 3 The employer shall inform an employee who has been subjected to an overexposure of the dose limit which is applicable to that employee for the remainder of the relevant dose limitation period. 4 In this regulation, “dose limitation period” means, as appropriate, a calendar year or the period of five consecutive calendar years. Part VI Arrangements for the Control of Radioactive Substances, Articles and Equipment Sealed sources and articles containing or embodying radioactive substances 27 1 Where a radioactive substance is used as a source of ionising radiation in work with ionising radiation, the radiation employer shall ensure that, whenever reasonably practicable, the substance is in the form of a sealed source. 2 The radiation employer shall ensure that the design, construction and maintenance of any article containing or embodying a radioactive substance, including its bonding, immediate container or other mechanical protection, is such as to prevent the leakage of any radioactive substance— a in the case of a sealed source, so far as is practicable; or b in the case of any other article, so far as is reasonably practicable. 3 Where appropriate, the radiation employer shall ensure that suitable tests are carried out at suitable intervals to detect leakage of radioactive substances from any article to which paragraph (2) applies and the employer shall make a suitable record of each such test and shall retain that record for at least 2 years after the article is disposed of or until a further record is made following a subsequent test to that article. Accounting for radioactive substances 28 For the purpose of controlling radioactive substances which are involved in work with ionising radiation which he undertakes, every radiation employer shall take such steps as are appropriate to account for and keep records of the quantity and location of those substances and shall keep those records or a copy thereof for at least 2 years from the date on which they were made and, in addition, for at least 2 years from the date of disposal of that radioactive substance. Keeping and moving of radioactive substances 29 1 Every radiation employer shall ensure, so far as is reasonably practicable, that any radioactive substance under his control which is not for the time being in use or being moved, transported or disposed of— a is kept in a suitable receptacle; and b is kept in a suitable store. 2 Every employer who causes or permits a radioactive substance to be moved (otherwise than by transporting it) shall ensure that, so far as is reasonably practicable, the substance is kept in a suitable receptacle, suitably labelled, while it is being moved. 3 Nothing in paragraphs (1) or (2) shall apply in relation to a radioactive substance while it is in or on the live body or corpse of a human being. Notification of certain occurrences 30 1 Every radiation employer shall forthwith notify the Executive in any case where a quantity of a radioactive substance which was under his control and which exceeds the quantity specified for that substance in column 4 of Schedule 8— a has been released or is likely to have been released into the atmosphere as a gas, aerosol or dust; or b has been spilled or otherwise released in such a manner as to give rise to significant contamination. 2 Paragraph (1) shall not apply where such release— a was in accordance with a registration under section 10 of the Radioactive Substances Act 1993 or which was exempt from such registration by virtue of section 11 of that Act; or b was in a manner specified in an authorisation to dispose of radioactive waste under section 13 of the said Act or which was exempt from such authorisation by virtue of section 15 of that Act. 3 Where a radiation employer has reasonable cause to believe that a quantity of a radioactive substance which exceeds the quantity for that substance specified in column 5 of Schedule 8 and which was under his control is lost or has been stolen, the employer shall forthwith notify the Executive of that loss or theft, as the case may be. 4 Where a radiation employer suspects or has been informed that an occurrence notifiable under paragraph (1) or (3) may have occurred, he shall make an immediate investigation and, unless that investigation shows that no such occurrence has occurred, he shall forthwith make a notification in accordance with the relevant paragraph. 5 A radiation employer who makes any investigation in accordance with paragraph (4) shall make a report of that investigation and shall, unless the investigation showed that no such occurrence occurred, keep that report or a copy thereof for at least 50 years from the date on which it was made or, in any other case, for at least 2 years from the date on which it was made. Duties of manufacturers etc. of articles for use in work with ionising radiation 31 1 In the case of articles for use at work, where that work is work with ionising radiation, Article 7(1) of the 1978 Order (which imposes general duties on manufacturers etc. as regards articles and substances for use at work) shall be modified so that any duty imposed on any person by that Article shall include a duty to ensure that any such article is so designed and constructed as to restrict so far as is reasonably practicable the extent to which employees and other persons are or are likely to be exposed to ionising radiation. 2 Where a person erects or installs an article for use at work, being work with ionising radiation, he shall— a where appropriate, undertake a critical examination of the way in which the article was erected or installed for the purpose of ensuring, in particular, that— i the safety features and warning devices operate correctly; and ii there is sufficient protection for persons from exposure to ionising radiation; b consult with the radiation protection adviser appointed by himself or by the radiation employer with regard to the nature and extent of any critical examination and the results of that examination; and c provide the radiation employer with adequate information about proper use, testing and maintenance of the article. Equipment used for medical exposure 32 1 Every employer who has to any extent control of any equipment or apparatus which is used in connection with a medical exposure shall, having regard to the extent of his control over the equipment, ensure that such equipment is of such design or construction and is so installed and maintained as to be capable of restricting so far as is reasonably practicable the exposure to ionising radiation of any person who is undergoing a medical exposure to the extent that this is compatible with the intended clinical purpose or research objective. 2 An employer who has to any extent control of any radiation equipment which is used for the purpose of diagnosis and which is installed after the date of the coming into operation of these Regulations shall, having regard to the extent of his control over the equipment, ensure that such equipment is provided, where practicable, with suitable means for informing the user of that equipment of the quantity of radiation produced by that equipment during a radiological procedure. 3 Every employer in respect of whom a duty is imposed by paragraph (1) shall, to the extent that it is reasonable for him to do so having regard to the extent of his control over the equipment, make arrangements for a suitable quality assurance programme to be provided in respect of the equipment or apparatus for the purpose of ensuring that it remains capable of restricting so far as is reasonably practicable exposure to the extent that this is compatible with the intended clinical purpose or research objective. 4 Without prejudice to the generality of paragraph (3), the quality assurance programme required by that paragraph shall require the carrying out of— a in respect of equipment or apparatus first used after the coming into operation of this regulation, adequate testing of that equipment or apparatus before it is first used for clinical purposes; b adequate testing of the performance of the equipment or apparatus at appropriate intervals and after any major maintenance procedure to that equipment or apparatus; c where appropriate, such measurements at suitable intervals as are necessary to enable the assessment of representative doses from any radiation equipment to persons undergoing medical exposures. 5 Every employer who has to any extent control of any radiation equipment shall take all such steps as are reasonably practicable to prevent the failure of any such equipment where such failure could result in an exposure to ionising radiation greater than that intended and to limit the consequences of any such failure. 6 Where a radiation employer suspects or has been informed that an incident may have occurred in which a person while undergoing a medical exposure was, as the result of a malfunction of, or defect in, radiation equipment under the control of that employer, exposed to ionising radiation to an extent much greater than that intended, he shall make an immediate investigation of the suspected incident and, unless that investigation shows beyond reasonable doubt that no such incident has occurred, shall forthwith notify the Executive thereof and make or arrange for a detailed investigation of the circumstances of the exposure and an assessment of the dose received. 7 A radiation employer who makes any investigation in accordance with paragraph (6) shall make a report of that investigation and shall— a in respect of an immediate report, keep that report or a copy thereof for a period of at least 2 years from the date on which it was made; and a in respect of a detailed report, keep that report or a copy thereof for a period of at least 50 years from the date on which it was made. 8 In this regulation, “radiation equipment” means equipment which delivers ionising radiation to the person undergoing a medical exposure and equipment which directly controls the extent of the exposure. Misuse of or interference with sources of ionising radiation 33 A person shall not intentionally or recklessly misuse or without reasonable excuse interfere with any radioactive substance or any electrical equipment to which these Regulations apply. Part VII Duties of Employees and Miscellaneous Duties of employees 34 1 An employee who is engaged in work with ionising radiation shall not knowingly expose himself or any other person to ionising radiation to an extent greater than is reasonably necessary for the purposes of his work, and shall exercise reasonable care while carrying out such work. 2 Every employee who is engaged in work with ionising radiation and for whom personal protective equipment is provided pursuant to regulation 8(2)( c ) shall— a make full and proper use of any such personal protective equipment; b forthwith report to his employer any defect he discovers in any such personal protective equipment; and c take all reasonable steps to ensure that any such personal protective equipment is returned after use to the accommodation provided for it. 3 It shall be the duty of every outside worker not to misuse the radiation passbook issued to him or falsify or attempt to falsify any of the information contained in it. 4 Any employee to whom regulation 21(1) or regulation 12(2)( b ) relates shall comply with any reasonable requirement imposed on him by his employer for the purposes of making the measurements and assessments required under regulation 20(1) and regulation 23(1). 5 An employee who is subject to medical surveillance under regulation 24 shall, when required by his employer and at the cost of the employer, present himself during his working hours for such medical examination and tests as may be required for the purposes of paragraph (2) of that regulation and shall provide the appointed doctor or employment medical adviser with such information concerning his health as the appointed doctor or employment medical adviser may reasonably require. 6 Where an employee has reasonable cause to believe that— a he or some other person has received an overexposure; b an occurrence mentioned in paragraph (1) or (3) of regulation 30 has occurred; or c an incident mentioned in regulation 32(6) has occurred, he shall forthwith notify his employer of that belief. Approval of dosimetry services 35 1 The Executive may, by a certificate in writing, approve (in accordance with such criteria as may from time to time be specified by the Executive) a suitable dosimetry service for such of the purposes of these Regulations as are specified in the certificate. 2 A certificate made pursuant to paragraph (1) may be made subject to conditions and may be revoked in writing at any time. 3 The Executive may at such suitable periods as it considers appropriate carry out a re-assessment of any approval granted pursuant to paragraph (1). Defence on contravention 36 1 In any proceedings against an employer for an offence under regulation 6(2), it shall be a defence for that employer to prove that— a he neither knew nor had reasonable cause to believe that he had carried out or might be required to carry out work subject to notification under that regulation; and b in a case where he discovered that he had carried out or was carrying out work subject to notification under that regulation, he had forthwith notified the Executive of the information required by that regulation. 2 In any proceedings against an employer for an offence under regulation 7, it shall be a defence for that employer to prove that— a he neither knew nor had reasonable cause to believe that he had commenced a new activity involving work with ionising radiation; and b in a case where he had discovered that he had commenced a new activity involving work with ionising radiation, he had as soon as practicable made an assessment as required by the said regulation 7. 3 In any proceedings against an employer for an offence under regulation 27(2) it shall be a defence for that employer to prove that— a he had received and reasonably relied on a written undertaking from the supplier of the article concerned that it complied with the requirements of that regulation; and b he had complied with the requirements of regulation 27(3). 4 In any proceedings against an employer of an outside worker for a breach of a duty under these Regulations it shall be a defence for that employer to show that— a he had entered into a contract in writing with the employer who had designated an area as a controlled area and in which the outside worker was working or was to work for that employer to perform that duty on his behalf; and b the breach of duty was a result of the failure of the employer referred to in sub-paragraph ( a ) to fulfil that contract. 5 In any proceedings against any employer who has designated a controlled area in which any outside worker is working or is to work, for a breach of a duty under these Regulations it shall be a defence for that employer to show that— a he had entered into a contract in writing with the employer of an outside worker for that employer to perform that duty on his behalf; and b the breach of duty was a result of the failure of the employer referred to in sub-paragraph ( a ) to fulfil that contract. 6 The person charged shall not, without leave of the court be entitled to rely on the defence referred to in paragraph (4) or (5) unless, within a period ending 7 clear days before the hearing, he has served on the prosecutor a notice in writing that he intends to rely on the defence and this notice shall be accompanied by a copy of the contract on which he intends to rely and, if that contract is not in English, an accurate translation of that contract into English.
