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
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.
