Current through Register Vol. 51, No. 1, July 1, 2024
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 regulate the possession or use of
				sources of ionizing or electronic product radiation and to regulate the
				handling and disposal of radioactive waste. The purpose of this administrative
				regulation is to provide requirements for the possession, use or operation of
				cabinet x-ray systems.
Section 1.
			 Applicability. This administrative regulation shall apply to persons who
			 possess, use or operate cabinet x-ray systems. This administrative regulation
			 does not apply to microscopic analytical x-ray systems.
Section 2. For cabinet x-ray systems
			 installed prior to April 10, 1975, the systems shall:
(1) Have the radiation machine and objects
			 exposed thereto, within a permanent enclosure, within which no person is
			 permitted to remain during the generation of x-radiation.
(2) Have adequate interlocks provided so that
			 if doors or panels to the enclosure are opened, the radiation-producing machine
			 is shut off automatically. After shutoff, it shall be possible to restore the
			 machine to full operation only from the control panel outside the
			 room.
(3) If the enclosure is of a
			 size or is so arranged that the operator cannot readily determine whether the
			 enclosure is unoccupied, there shall be provided:
(a) Audible or visible warning signals within
			 the enclosure which are required to be activated before irradiation can be
			 started.
(b) Suitable means of
			 exit, so that a person who accidentally may be shut in can leave the enclosure
			 without delay, or effective means within the enclosure for preventing or
			 quickly interrupting the irradiation, and which cannot be reset from outside
			 the enclosure.
(4)
			 Except as provided in subsection (5) of this section, the exposure at
			 accessible regions two (2) inches from the outside surface of the enclosure
			 cannot exceed five-tenths (0.5) milliroentgen in one (1) hour.
(5) If the registrant has submitted operating
			 and safety procedures, and the cabinet has approved the procedures, which can
			 show that an individual cannot receive a radiation dose in excess of the limits
			 specified in these administrative regulations, the radiation levels specified
			 in subsection (4) of this section may be exceeded. However, cabinet x-ray
			 systems under this subsection shall not exceed the limits specified below:
(a) The exposure at accessible and occupied
			 areas one (1) foot from the outside surface of the enclosure shall not exceed
			 ten (10) milliroentgens in one (1) hour.
(b) The exposure at accessible and normally
			 unoccupied areas one (1) foot from the outside surface of the enclosure shall
			 not exceed 100 milliroentgens in one (1) hour.
(6) Operating procedures.
(a) Before a new installation is placed in
			 routine operation, a radiation protection survey shall be made. This shall also
			 be done after changes in an existing installation which might affect its
			 radiation safety.
(b) A copy of
			 each radiation protection survey shall be signed and dated by the surveyor, and
			 kept on file by the individual in charge of the installation.
(c) The installation shall be operated in
			 conformance with recommendations of the protection survey.
(d) The registrant shall designate a
			 competent employee as the radiation safety officer.
