Current through Vol. 24-12, July 15, 2024
Rule 333.
(1)
						An operator shall properly utilize the beam-limiting devices provided to
						restrict the useful beam to the smallest area consistent with clinical
						requirements. Particular care shall be taken to align accurately the x-ray beam
						with the patient and film.
(2) The
						operator shall ensure the presence of adequate filtration before a radiographic
						procedure.
(3) Staff personnel
						routinely working with or around radiation sources shall not be required by the
						registrant to hold film or restrain patients during radiography. If such
						procedure is permitted, personnel exposure shall not exceed the limits in R
						333.5057 to R 333.5059 or the procedure shall be prohibited.
(4) When a patient must be held in position
						for radiography, mechanical supporting or restraining devices shall be
						available and shall be used unless contraindicated. If the patient must be held
						by an individual, this individual shall wear protective gloves and a protective
						apron of 0.5 millimeter minimum lead equivalence and shall be positioned so
						that no part of his or her body can be struck by the useful beam and that his
						or her body is as far as possible from the edge of the useful beam.
(5) Only individuals whose presence is
						necessary shall be permitted in the radiographic room during an exposure. An
						individual, except the patient, shall be protected by 0.5 millimeter minimum
						lead equivalent aprons unless protected by an approved primary
						barrier.
(6) Personnel monitoring
						shall be performed in controlled areas for each individual occupationally
						exposed to ionizing radiation from diagnostic x-ray eq uipment. Individual
						monitoring devices such as film badge dosimeters or thermoluminescent
						dosimeters shall be permanently assigned to each occupationally exposed
						individual. This monitoring shall be continuous during employment as a
						radiation worker.
(7) Personnel
						exposure records shall be kept on permanent available file at the facility
						where the exposure occurs.
(8)
						Monitoring devices used to estimate whole body exposure shall normally be worn
						on the chest or abdomen. Monitoring of all other body parts shall comply with R
						333.5065.
(9) Monitoring devices
						worn to estimate personnel occupational exposure shall not be worn by the
						individual when he or she is exposed as a patient for a medical or dental
						reason.
(10) The gonads of children
						and individuals who have not passed the reproductive age shall be protected
						from the useful beam either by the use of shielding (0.5 mm lead equivalent),
						collimation, or special gonad shields when this does not interfere with the
						conditions or objectives of the examination.
(11) Intensifying screens shall be employed
						to reduce patient exposure except in cases where a noticeable decrease in image
						definition may reduce the clinical value of the examination. Film and screen
						speed combinations shall be carefully selected to produce the necessary
						clinical information with the least exposure to the patient consistent with
						current clinical judgment.
(12)
						Film processing materials and techniques shall be those recommended by the
						x-ray film and processing materials manufacturers unless otherwise tested to
						ensure maximum information content of the developed film. Sight developing is
						not permitted except under extreme emergency conditions. Correct temperature
						control and development time shall be used.
(13) A radiographic x-ray system shall not be
						left unattended without locking the apparatus, room, or building in some manner
						which prevents use of the apparatus by unauthorized persons.
