RELATES TO: KRS 211.842-211.852,
				211.990(4)
NECESSITY, FUNCTION, AND CONFORMITY: The Cabinet for Human
				Resources is authorized by
				KRS
				211.844 to provide by administrative
				regulation for the registration and licensing of the possession or use of a
				source of ionizing or electronic product radiation and the handling and
				disposal of radioactive waste. The purpose of this administrative regulation is
				to provide general requirements for the possession, use, and operation of x-ray
				systems.
Section 1. Applicability. This
			 administrative regulation shall apply to x-ray systems and persons, equipment,
			 and materials used in connection with the possession, use, or operation of
			 these systems. X-ray systems shall comply with the requirements of this
			 administrative regulation and with other administrative regulations pertinent
			 to the particular system employed.
Section
			 2. Administrative Control.
(1) No
			 person shall make, sell, lease, transfer, lend, or install x-ray systems or the
			 accessories used in connection with the systems unless the accessories and
			 systems, if properly placed in operation and properly used, meet the
			 requirements of these administrative regulations. These provisions include, but
			 are not limited to, the delivery of cones or collimators, filters, adequate
			 timers, and fluoroscopic shutters, if applicable.
(2) The registrant shall be responsible for
			 directing the operation of the x-ray systems he has registered with the
			 cabinet. In the operation of the x-ray system, the registrant or his agent
			 shall ensure that the following requirements are met:
(a) An x-ray system which does not meet the
			 provisions of these administrative regulations shall not be operated unless a
			 specific exemption in writing has been granted by the cabinet. If the
			 registrant advises an agent of the cabinet that he no longer uses an x-ray
			 system, the cabinet may inactivate the system. Inactivated x-ray systems may be
			 reactivated only by the cabinet or with its written permission. Inactivation of
			 an x-ray system may be accomplished by one (1) of the following means:
1. An inactivation seal(s), numbers and
			 instructions approved by the cabinet, may be placed on an x-ray system so as to
			 prevent energizing the system. X-ray systems so sealed as inactive shall not be
			 utilized and the seal or attached instructions shall not be removed without the
			 express authorization of the cabinet.
2. The cabinet may approve the removal of
			 portions of the x-ray system so as to render the system inoperative or so as to
			 allow only those portions of the system to remain operative which are in
			 compliance with these administrative regulations. X-ray systems or portions of
			 x-ray systems having been so inactivated shall not be operated or be made
			 operative by reinstallation of the removed portions of the system without the
			 express authorization of the cabinet. X-ray systems so inactivated shall be
			 clearly labeled showing the limitations of the x-ray system. The labels shall
			 not be removed without the express authorization of the cabinet.
(b) Individuals operating x-ray
			 systems shall be adequately instructed in safe operating procedures and shall
			 be competent in the safe use of the system.
(c) Written safety procedures and rules for
			 the particular x-ray system shall be posted in a conspicuous place beside each
			 x-ray system's control panel and a copy of these administrative regulations
			 shall be made available in each general work area.
(d) The following exposures are prohibited:
1. Exposure of an individual to the useful
			 beam for training or demonstration purposes; and
2. Exposure of individuals for the purpose of
			 mass screenings, except if authorized by a licensed practitioner of the healing
			 arts within the scope of his professional license.
(e) If a patient or film is provided with
			 auxiliary support during a radiation exposure, the registrant shall:
1. Provide mechanical holding devices to be
			 used if the technique permits;
2.
			 Provide written safety procedures, as required by this administrative
			 regulation, which shall indicate the requirements for selecting a person to
			 hold a patient or film and the procedure which the holder shall
			 follow;
3. Provide the human holder
			 with protection from radiation exposure as required by these administrative
			 regulations; and
4. Ensure that no
			 person is used routinely to hold film or patients.
(f) If protective clothing is worn on
			 portions of the body and a monitoring device(s) are required, at least one (1)
			 monitoring device shall be utilized as follows:
1. If an apron is worn, the monitoring device
			 shall be worn at the neck area outside of the apron; and
2. If more than one (1) device is used and a
			 record is made of the data, each dose shall be identified with the area where
			 the device was worn on the body.
(g) A personnel monitoring device shall not
			 be exposed to deceptively indicate a dose delivered to an individual.
(h) The registrant shall maintain the
			 following information for each x-ray system for inspection by the cabinet:
1. Maximum rating of technique
			 factors;
2. Tube rating charts and
			 cooling curves; and
3. Records of
			 surveys, calibrations, maintenance and modifications performed on the x-ray
			 system along with the names of persons who performed the service; and
4. For equipment registered after the
			 effective date of these administrative regulations, aluminum equivalent
			 filtration of the useful beam, including routine variations.
(i) Each installation shall be
			 provided with primary barriers and secondary barriers as are necessary to
			 ensure compliance with these administrative regulations. This requirement shall
			 be deemed to be met, if the thickness of barriers are equivalent to those as
			 computed in accordance with the National Council of Radiation Protection Report
			 No. 49, "Structural Shielding Design and Evaluation for Medical Use of X-rays
			 and Gamma Rays of Energies up to 10 MeV"; and
1. Doors that are an integral part of primary
			 and secondary barriers shall be closed during x-ray procedures; and
2. Doors in Section subparagraph 1 of this
			 paragraph "CLOSE DOOR DURING X-RAY PROCEDURES".
(j) If a darkroom is used in connection with
			 an x-ray system the following requirements shall apply:
1. The darkroom shall be constructed so that
			 film being processed, handled, or stored is exposed only to light which has
			 passed through a safe light filter; and
2. Adequate safety lighting shall be provided
			 in each darkroom so that the radiance and spectral emissions of the safelight,
			 bulb and filter combination shall not fog (the film) above the base fog level
			 if exposed for one (1) minute at a distance of 120 centimeters from the
			 lamp(s). Film manufacturer's recommendations for a safelight and its placement
			 shall be adjudged to meet this criterion.
(k) Automatic processors and other closed
			 processing systems shall meet the following requirements:
1. Preventive maintenance shall be performed
			 on the unit, except for extended periods of non-use, on a frequency basis which
			 is not less than that schedule recommended by the manufacturer. If no schedule
			 is available from the manufacturer, a maintenance schedule shall be established
			 which preserves good film quality; and
2. After a full cleansing of the processor, a
			 film shall be exposed to a density of approximately one (1), with one-half
			 (1/2) of the film protected from the exposure. The film shall be developed,
			 kept near the unit and at least one (1) test film daily (exposed under
			 techniques identical with those used for the original test film) shall be
			 compared with the original test film to evaluate the adequacy of the unit's
			 developing capability and base fog level.
(l) Manual processing systems shall meet the
			 following requirements:
1. A device shall be
			 available which indicates the actual temperature of the developer in degrees
			 Fahrenheit or Celsius;
2. The
			 amount of time that the film remains in the developer solution shall be
			 controlled. At the end of a preset time interval, the timing mechanism used for
			 controlling the development time shall provide a visible or audible
			 signal;
3. A time-temperature
			 technique consistent with the film or developer manufacturer's requirements
			 shall be used; and
4. A temperature
			 control system shall be available to maintain the temperature of the developing
			 solution within the range specified by the manufacturer. A means shall be
			 provided to control the temperature of the fixer and the rinse water to within
			 five (5) degrees Fahrenheit of the temperature of the developer solution.
			 Exceptions to the requirements of this subparagraph may be authorized by the
			 cabinet on the basis of a written request providing details of the developing
			 procedure to be used, methods of controlling developing conditions, and an
			 adequate justification for the exception.
