Radiation risk assessments 8 1 An employer, before commencing a new activity involving work with ionising radiation in respect of which no risk assessment has been made by that employer, shall make a suitable and sufficient assessment of the risk to any employee and other person for the purpose of identifying the measures the employer needs to take to restrict the exposure of that employee or other person to ionising radiation. 2 Without prejudice to paragraph (1), an employer shall not carry out work with ionising radiation unless it 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 employer who is subject to the obligation in paragraph (1) to make the risk assessment shall take all reasonably practicable steps to— a prevent any such accident; b limit the consequences of any accident which does occur; and c provide employees with the information, instruction, training and 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) 2000 . Restriction of exposure 9 1 Every employer shall, in relation to any work with ionising radiation that it undertakes, take all necessary steps to restrict so far as is reasonably practicable the extent to which its employees and other persons are exposed to ionising radiation. 2 Without prejudice to the generality of paragraph (1), an employer in relation to any work with ionising radiation that it undertakes shall— a so far as is reasonably practicable achieve the restriction of exposure to ionising radiation required under paragraph (1) by means of engineering controls, design features and by the provision and use of safety features and warning devices; b 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 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 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. 4 Where it is appropriate to do so at the planning stage of radiation protection, an employer, in relation to any work with ionising radiation that it undertakes, shall use dose constraints in restricting exposure to ionising radiation pursuant to paragraph (1). 5 An employer shall establish the dose constraints referred to in paragraph (4) in terms of the effective or equivalent dose received by an individual over an appropriate period of time. 6 Without prejudice to paragraph (1), an employer who undertakes work with ionising radiation shall ensure that— a in relation to an employee who is pregnant, the conditions of exposure are such that, after the employee's employer has been notified of the pregnancy, the equivalent dose to the foetus is as low as is reasonably practicable and is unlikely to exceed 1 mSv during the remainder of the pregnancy; and b in relation to an employee who is breastfeeding, that employee shall not be engaged in any work involving a significant risk of intake of radionuclides or of bodily contamination. 7 Nothing in paragraph (6) requires the employer who undertakes work with ionising radiation to take any action in relation to an employee until that employee's employer has been notified in writing by the employee of the pregnancy or that the employee is breastfeeding and the employer who is undertaking the work with ionising radiation has been made aware, or should reasonably have been expected to be aware, of that notification. 8 Every employer shall, for the purpose of determining whether the requirements of paragraph (1) are being met, ensure that an investigation is carried out without delay when the effective dose of ionising radiation received by any of its employees for the first time in any calendar year exceeds 15 mSv 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 18(1) or, where local rules are not required, by other suitable means. Personal protective equipment 10 1 Any personal protective equipment provided by an employer pursuant to regulation 9 shall be suitable for its purpose and a comply with any legal requirement which is applicable to that item of personal protective equipment; or b in the case of respiratory protective equipment where no provision referred to in sub-paragraph (a) applies, be of a type approved or conform to a standard approved, in either case, by- i the Executive; or ii the Great Britain Executive under regulation 10 (1) (b) of the Great Britain Regulations. 2 Every employer who provides personal protective equipment pursuant to regulation 9 shall ensure that adequate facilities are provided for the storage of that equipment. 3 In paragraph (1)(a), “legal requirement” means any requirement of the Personal Protective Equipment Regulations 2002 or Regulation ( EU ) 2016/425 of the European Parliament and of the Council on personal protective equipment and repealing Council Directive 89/686/EEC ( OJ No L81, 31.3.2016, p51). Maintenance and examination of engineering controls etc and personal protective equipment 11 1 An employer who provides any engineering control, design feature, safety feature or warning device to meet the requirements of regulation 9(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 employer shall ensure that— a all personal protective equipment provided pursuant to regulation 9 is, where appropriate, thoroughly examined at suitable intervals and is properly maintained; and b in the case of respiratory protective equipment, a suitable record of that examination is made and kept for at least 2 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 12 1 Subject to paragraph (2), every employer shall ensure that its employees and other persons within a class specified in Schedule 3 are not exposed to ionising radiation to an extent that any dose limit specified in Part 1 of that Schedule for such class of person is exceeded in any calendar year. 2 Where an employer is able to demonstrate to the Executive that, in respect of an employee, the dose limit specified in paragraph 1 of Part I of Schedule 3 is impracticable having regard to the nature of the work undertaken by that employee, the Executive may in respect of that employee authorise the employer to apply the dose limits set out in paragraphs 8 or 9 of Schedule 3 and in such case the provisions of Part 2 of that Schedule will have effect. 3 The steps taken by a relevant employer to comply with paragraph (1) in respect of members of the public shall include an estimation of doses to members of the public from the relevant practice or practices carried out by the relevant employer in accordance with requirements regarding the estimation of doses as approved by the Executive from time to time. 4 In this regulation— “ relevant employer ” means an employer who is carrying out, or who intends to carry out, a relevant practice; “ relevant practice ” means a practice to which regulation 6 or 7 applies. Contingency plans 13 1 Where an assessment made in accordance with regulation 8 shows that a radiation accident is reasonably foreseeable (having regard to the steps taken by the employer under paragraph (3) of that regulation), the 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 An employer shall ensure that— a where local rules are required for the purposes of regulation 18, 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 the employer's control who may be involved with or affected by arrangements in the plan has been given suitable and sufficient instructions and where appropriate issued with suitable dosemeters or other devices; c where appropriate, rehearsals of the arrangements in the plan are carried out at suitable intervals; and d if circumstances arise where it is necessary for some or all of the arrangements in the plan to be carried out— i the cause of those circumstances is analysed to determine, so far as is reasonably practicable, the measures, if any, required to prevent a recurrence of such circumstances; ii a record of such analysis is made and kept for at least 2 years from the date on which it was made; and iii any exposure which occurs due to the above circumstances is noted on any relevant dose record.

Information, instruction and training 15 1 Every employer shall ensure that— a those of its 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 as a result of their work; ii the general and specific radiation protection procedures and precautions which should be taken in connection with the work with ionising radiation to which they may be assigned; 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; c its female employees 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 their informing their employer in writing as soon as possible— i after becoming aware of their pregnancy; or ii if they intend to breast feed an infant; d any employees engaged in work in a controlled area (as designated under regulation 17) are given specific training in connection with the characteristics of the workplace and the activities within it; and e the giving of training and information under this regulation is repeated at appropriate intervals and documented by the employer. 2 In addition to the requirements in paragraph (1), every employer who is engaged in work with ionising radiation involving a high-activity sealed source shall ensure that the information and training given to employees involved in such work includes— a specific requirements for the safe management and control of high-activity sealed sources for the purpose of preparing such employees for any events which may affect their radiation protection; b particular emphasis on the necessary safety requirements in connection with high-activity sealed sources; and c specific information on the possible consequences of the loss of adequate control of high-activity sealed sources. Co-operation between employers 16 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— a has access to information on the possible exposure of their employees to ionising radiation; and b is enabled to comply with the requirements of these Regulations in so far as their ability to comply depends upon such co-operation. PART 4 DESIGNATED AREAS Designation of controlled or supervised areas 17 1 Every employer shall designate as a controlled area any area under its control which has been identified by an assessment made by that employer (whether pursuant to regulation 8 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 than 6 mSv a year or an equivalent dose greater than 15 mSv a year for the lens of the eye or greater than 150 mSv a year for the skin or the extremities. 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 its 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 1 mSv a year or an equivalent dose greater than 5 mSv a year for the lens of the eye or greater than 50 mSv a year for the skin or the extremities. Local rules and radiation protection supervisors 18 1 For the purposes of enabling work with ionising radiation to be carried on in accordance with the requirements of these Regulations, every employer engaged in work with ionising radiation 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 Local rules shall identify the main working instructions intended to restrict any exposure in that controlled or supervised area. 3 An employer shall take all reasonable steps to ensure that any local rules which are relevant to the work being carried out are observed. 4 An employer shall ensure that any relevant local rules are brought to the attention of those employees and other persons who may be affected by them. 5 An 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; b set down in the local rules the names of such radiation protection supervisors; and c provide the means necessary for such radiation protection supervisors to perform their role. Additional requirements for designated areas 19 1 Every employer who designates any area as a controlled or supervised area shall ensure that any such designated area— a is adequately described in local rules; and b has suitable and sufficient signs displayed in suitable positions warning that the area has been so designated and indicating the nature of the radiation sources and the risks arising from such sources. 2 A controlled area shall be physically demarcated or, where this is not reasonably practicable, delineated by some other suitable means. 3 The employer who has designated an area as a controlled area shall not permit any person to enter or remain in that area unless they— a are a classified person who is not a classified outside worker; b are a classified outside worker in respect of whom that employer has taken all reasonable steps to ensure that the person— i is subject to individual dose assessment pursuant to regulation 22; ii has been provided with and has been trained to use any personal protective equipment that may be necessary pursuant to regulation 9(2)(c); iii has received any specific training required pursuant to regulation 15; and iv has been certified fit pursuant to regulation 25 for the work with ionising radiation which the person is to carry out; or c not being a classified person, have entered or remain in the area in accordance with suitable written arrangements. 4 The written arrangements referred to in paragraph (3)(c) shall ensure that— a an employee or a non-classified outside worker aged 18 years or over, does not receive in any calendar year a cumulative dose of ionising radiation which would require that person to be designated as a classified person; or b any other person does not receive in any calendar year a dose of ionising radiation exceeding any relevant dose limit. 5 A non-classified outside worker is not permitted to enter or remain in a controlled area pursuant to paragraph (3)(c) unless they have been provided with personal protective equipment and training pursuant to paragraph (3)(b)(ii) and (iii). 6 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 written arrangements pursuant to paragraph (3)(c) unless the employer can demonstrate, by personal dose monitoring or other suitable measurements, that the doses are restricted in accordance with paragraph (4). 7 An employer who has designated an area as a controlled area shall, in relation to a classified outside worker, ensure that— a the classified outside worker is subject to arrangements for estimating the dose of ionising radiation received by that worker whilst in the controlled area; b as soon as is reasonably practicable after the services carried out by that classified outside worker in that controlled area are completed, an estimate of the dose received by that worker is entered into that worker's radiation passbook; and c when the radiation passbook of the classified outside worker is in the possession of that employer, the passbook is made available to that worker upon request. 8 The employer who carries out the monitoring or measurements pursuant to paragraph (6) 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. 9 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. 10 Without prejudice to the generality of paragraph (9), 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 any similar activity to result in the ingestion, inhalation or absorption of a radioactive substance by any employee or outside worker in a controlled area; and d the means for monitoring contamination— i within a controlled area and, where appropriate, in the adjacent area; and ii on any person, article or goods leaving a controlled area. Monitoring of designated areas 20 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 Adequate monitoring referred to in paragraph (1) shall include— a in relation to areas designated on the basis of external radiation, measurement of dose rates (averaged over a suitable period if necessary); and b in relation to areas designated on the basis of internal radiation, measurements where appropriate of air activity and surface contamination taking into account the physical and chemical states of the radioactive contamination. 3 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; and b be adequately tested and examined at appropriate intervals. 4 Equipment provided pursuant to paragraph (3) 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 (3) and sub-paragraph (a) have been carried out by or under the supervision of a suitably qualified person. 5 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 (3) and (4); b ensure that the records of the tests carried out in accordance with paragraphs (3) and (4) are authorised by a suitably qualified person; and c keep the records referred to in sub-paragraph (a), or copies of those records, for at least 2 years from the respective dates on which they were made. 6 Suitable records of the results of the monitoring referred to in paragraph 5(a) shall include— a in relation to areas designated on the basis of external radiation, an indication of the nature and quality of the radiation in question; b in relation to areas designated on the basis of internal radiation, an indication, where appropriate, of the nature and physical and chemical states of the radioactive contamination. PART 5 CLASSIFICATION AND MONITORING OF PERSONS Designation of classified persons 21 1 Subject to paragraph (2), the employer shall designate as classified persons those of its employees who are likely to receive an effective dose greater than 6 mSv per year or an equivalent dose greater than 15 mSv per year for the lens of the eye or greater than 150 mSv per year for the skin or the extremities and shall immediately 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 a relevant doctor has certified in the health record that that employee is fit for the work with ionising radiation which that employee 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 a relevant doctor 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 22 1 Every employer shall ensure that— a in respect of each of its 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 of those records, 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 30 years from when the record was made; b to provide the employer at appropriate intervals with suitable summaries of the maintained dose records; c when and as required by the employer, to provide the employer with copies of the dose record relating to any of the employer's employees; 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 of the record to the employer as soon as possible, and such a record 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 23, 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 a classified outside worker, to provide, where appropriate, a current radiation passbook in respect of that classified outside worker; and i where the employer employs a classified outside worker who works in Great Britain or a member State , to maintain a continuing record of the assessment of the dose received by that classified outside worker when working in such place. 4 The employer shall provide the approved dosimetry service with such information concerning its 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 classified outside worker employed by it 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 5; and b make suitable arrangements to ensure that the particulars entered in the radiation passbook are kept up-to-date during the period of employment of the classified outside worker by that employer. 6 The employer shall— a at the request of a classified person employed by the employer (or of a person formerly employed by the employer 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; and 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 that person with a copy of their 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 and notional doses and special entries 23 1 Where a dosemeter or other device is used to make any individual measurement under regulation 22(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— a 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— i in a case where there is adequate information to estimate the dose received by that person, send to the approved dosimetry service an adequate summary of the information used to estimate that dose and arrange for the approved dosimetry service to enter the estimated dose in the dose record of that person; or ii in a case where there is inadequate information to estimate the dose received by the classified person, 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 b in either case referred to in sub-paragraph (a), take reasonable steps to inform the classified person of the entry in their dose record and arrange for the approved dosimetry service to identify that entry 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 paragraph (1)(a). 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, the employer shall make an adequate investigation of the circumstances of the exposure of that person to ionising radiation and, if that investigation confirms the employer's belief, the employer shall, where there is adequate information to estimate the dose received by the classified person— 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) that person may, by an application in writing to the Executive made within 3 months of the date on which that person 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, require the approved dosimetry service to 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— a the cumulative recorded effective dose is 20 mSv 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 24 1 Where any accident or other occurrence takes place which is likely to result in a person receiving an effective dose of ionising radiation greater than 6 mSv or an equivalent dose greater than 15 mSv for the lens of an eye or greater than 150 mSv for the skin or the extremities, the employer shall— a in the case of a classified person, arrange for a dose assessment to be made by the approved dosimetry service as soon as possible; b in the case of an employee to whom a dosemeter or other device has been issued in accordance with regulation 13(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 each such 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; b notify the Executive of the result of the dose assessment as soon as possible; and c keep a record or copy of the assessment 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 30 years from the date of the relevant accident. Medical surveillance 25 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 in respect of whom a relevant doctor has made a certification under paragraph (5). 2 An employer shall ensure that— a each of its employees to whom this regulation relates is under adequate medical surveillance by a relevant doctor for the purpose of determining the fitness of each employee for the work with ionising radiation which that employee is to carry out; b a health record containing the particulars referred to in Schedule 6 is made and maintained in respect of such employees; and c the record or a copy of the record 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 30 years from the date of the last entry made in it. 3 Subject to paragraph (4), an employer shall ensure that there is a valid entry made by a relevant doctor in the health record of each of its employees to whom this regulation relates (other than employees who have received an overexposure and who are not classified persons) and an entry in the health record is valid— a for 12 months from the date it was made or treated as made by virtue of paragraph (4); b for such shorter period as is specified in the entry by the relevant doctor; or c until cancelled by a relevant doctor by a further entry in the record. 4 For the purposes of paragraph (3)(a), a further entry in the health record of the same employee, where made not less than 11 months nor more than 13 months after the start of the current period of validity, is to be treated as if made at the end of that period. 5 Where a relevant doctor has certified in the health record of an employee that in their professional opinion that employee should not be engaged in work with ionising radiation or that the employee should only be so engaged under conditions specified by the relevant doctor in the health record, the employer shall not permit that employee to be engaged in the work with ionising radiation, or only permit the employee to be engaged in the work in accordance with the conditions so specified, as the case may be. 6 Where a relevant doctor requires to inspect any workplace for the purpose of carrying out their functions under these Regulations the employer shall permit them to do so. 7 An employer shall make available to the relevant doctor the summary of the dose record kept by the employer pursuant to regulation 22(7) and such other records kept for the purposes of these Regulations as the relevant doctor may reasonably require. 8 Where an employee is aggrieved by a decision recorded in the health record by a relevant doctor the employee may, by an application in writing to the Executive made within 28 days of the date on which the employee 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 the employee's health record in accordance with the approved procedure. Investigation and notification of overexposure 26 1 Where an employer suspects or has been informed that any person is likely to have received an overexposure as a result of work with ionising radiation 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 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 the employer's own employee, the relevant doctor; b as soon as practicable take reasonable steps to notify the suspected overexposure to the person affected; 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 d immediately notify the results of the investigation and assessment referred to in sub-paragraph (c) to the persons and authorities mentioned in sub-paragraph (a) and shall— i in the case of the employer's employee, immediately notify that employee of the results of the investigation and assessment; or ii in the case of a person who is not the employer's employee, where the investigation has shown that that person has received an overexposure, take all reasonable steps to notify that person of their overexposure. 2 An 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 of the report for at least 2 years from the date on which it was made; and b in respect of an investigation made pursuant to paragraph (1)(c), keep that report or a copy of the report 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 30 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, the employee's employer shall arrange for the assessment of the dose received to be entered into that dose record. Dose limitation for overexposed employees 27 1 Without prejudice to other requirements of these Regulations and in particular regulation 25(5), where an employee has been subjected to an overexposure paragraph (2) applies in relation to the employment of that employee on work with ionising radiation during the remainder of the dose limitation period, where that remaining period commences at the end of the personal dose assessment period in which that employee 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 6 ARRANGEMENTS FOR THE CONTROL OF RADIOACTIVE SUBSTANCES, ARTICLES AND EQUIPMENT Sealed sources and articles containing or embodying radioactive substances 28 1 Where a radioactive substance is used as a source of ionising radiation in work with ionising radiation, the employer shall ensure that, whenever reasonably practicable, the substance is in the form of a sealed source. 2 The 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 The employer shall— a ensure that, where appropriate, suitable tests are carried out at suitable intervals to detect leakage of radioactive substances from any article to which paragraph (2) applies; and b make a suitable record of each such test and 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 29 Every employer, for the purpose of controlling radioactive substances which are involved in work with ionising radiation undertaken by that employer, shall— a take such steps as are appropriate to account for and keep records of the quantity and location of those substances; and b keep those records or a copy of the records 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 30 1 An employer shall ensure, so far as is reasonably practicable, that any radioactive substance under its 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 An 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) applies 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 31 1 An employer shall immediately notify the Executive in any case where a quantity of a radioactive substance which was under its control and which exceeds the quantity specified for that substance in column 5 of Part I of Schedule 7— 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 that Act or which was exempt from such authorisation by virtue of section 15 of that Act. 3 Where an employer has reasonable cause to believe that a quantity of radioactive substance which exceeds the quantity for that substance specified in column 6 of Part I of Schedule 7 and which was under its control is lost or has been stolen, the employer shall immediately notify the Executive of that loss or theft, as the case may be. 4 Where an employer suspects or has been informed that an occurrence notifiable under this regulation may have occurred, it shall make an immediate investigation and, unless that investigation shows that no such occurrence has occurred, it shall immediately make a notification under the relevant paragraph of this regulation. 5 An 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 of the report for at least 30 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 32 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) is modified so that any duty imposed on any person by that Article includes 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, that person shall— a undertake a critical examination of the way in which the article was erected or installed for the purpose of ensuring, in particular, that— i any 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 that they appointed, or that the employer engaged in work with ionising radiation appointed, with regard to the nature and extent of any critical examination and the results of that examination; and c provide the employer engaged in work with ionising radiation with adequate information about proper use, testing and maintenance of the article. Equipment used for medical exposure 33 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Misuse of or interference with sources of ionising radiation 34 No person may intentionally or recklessly misuse or without reasonable excuse interfere with any radioactive substance or any electrical equipment in respect of which these Regulations apply. PART 7 DUTIES OF EMPLOYEES AND MISCELLANEOUS Duties of employees 35 1 An employee who is engaged in work with ionising radiation shall not knowingly expose themselves or any other person to ionising radiation to an extent greater than is reasonably necessary for the purposes of their work, and shall exercise reasonable care while carrying out such work. 2 Every employee or outside worker for whom personal protective equipment is provided pursuant to regulation 9(2)(c) shall— a make full and proper use of any such personal protective equipment; b immediately report to the employer who provided any such personal protective equipment any defect they discover in that 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 is the duty of every classified outside worker not to misuse the radiation passbook issued to that worker or falsify or attempt to falsify any of the information contained in it. 4 Any employee to whom regulation 22(1) or regulation 13(2)(b) relates shall comply with any reasonable requirement imposed on that person by that person's employer for the purposes of making the measurements and assessments required under regulation 22(1) and regulation 24(1). 5 An employee who is subject to medical surveillance under regulation 25 shall, when required by their employer and at the cost of the employer, present themselves during their working hours for such medical examination and tests as may be required for the purposes of regulation 25(2) and shall provide the relevant doctor with such information concerning their health as the relevant doctor may reasonably require. 6 Where an employee has reasonable cause to believe that— a they or some other person has received an overexposure or ; b an occurrence mentioned in paragraph (1) or (3) of regulation 31 has occurred; ... c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . they shall immediately notify their employer of that belief.
