211.842-211.852, 211.990(4)

      STATUTORY

AUTHORITY: KRS 194.050, 211.090, 211.844

      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 sources of ionizing or electronic product

radiation and the handling and disposal of radioactive waste. The purpose of

this administrative regulation is to provide special requirements for the

possession, use, and operation of radiographic x-ray systems for veterinary

medicine purposes.

 

      Section 1.

Applicability. This administrative regulation shall apply to radiographic x-ray

systems for veterinary medicine and to persons, equipment, and materials used

in connection with the possession, use or operation of these systems.

 

      Section 2.

Equipment. Veterinary radiographic x-ray systems shall meet the following

requirements:

      (1) The

protective tube housing assembly shall be of the diagnostic type;

      (2) The primary

beam shall be restricted by cones, shutters, diaphragms, or adjustable

collimators. No dimension of the x-ray field, measured in the plane of the

image receptor, shall exceed the corresponding dimension of the image receptor by

more than two (2) percent of the source to image receptor distance (SID)

measured if the plane of the image receptor is perpendicular to the primary ray

of the x-ray field. This paragraph shall not be construed to require enlarging

the x-ray field size if the x-ray field size is less than the size of the image

receptor.

      (3) A means

shall be provided to align the center of the x-ray field with the center of the

image receptor to within two (2) percent of the source to image receptor

distance;

      (4) A device

shall be provided to terminate the exposure after a preset time or exposure;

and

      (5) A dead man

type of exposure switch shall be provided, together with an electrical cord of

sufficient length, so that the operator can conveniently stand at least one and

eight-tenths (1.8) meters from the tube housing assembly, the animal, and the

useful beam during x-ray exposures if the exposure to the operator is within

the limits provided by 902 KAR 100:020, Section 20.

 

      Section 3.

Structural Shielding. Wall, ceiling, and floor areas shall be equivalent to or

provided with applicable protective barriers as required by 902 KAR 100:105,

Section 2(2)(i).

 

      Section 4.

Operating Procedures. In the operation of a veterinary radiographic x-ray

system the following requirements shall be met:

      (1) The operator

shall stand well away from the useful beam and the animal during radiographic

exposures. No individual other than the operator shall be in the x-ray room

while exposures are being made unless an individual's assistance is required;

and

      (2) If an animal

is held in position during radiography, mechanical supporting or restraining

devices shall be available and used if possible. If an animal is held by an

individual, that individual shall be protected with appropriate shielding

devices (protective gloves and apron), and shall be so positioned that no part

of his body shall be struck by the useful beam. In addition, the exposure of an

individual used for this purpose shall be monitored and no individual shall

routinely be used to hold animals. (1 Ky.R. 416; eff. 2-5-75; Am. 3 Ky.R. 561;
