Rule 713.
(1)
					 The CT facility shall establish scanning protocols in consultation with the
					 medical physicist.
(2) The CT
					 operator shall check the display panel before and after performing each scan to
					 make sure the amount of radiation delivered is appropriate for the technique
					 and individual patient. This may be accomplished by reviewing dose indicator
					 devices, if available, or dose indices such as the technique factors. Dose
					 indicators or indices outside of expected values shall be documented and
					 reviewed by an interpreting physician or medical physicist.
(3) A fixed CT scanner shall be operated from
					 a shielded position behind a protective barrier pursuant to R
					 333.5711(4).
(4) Staff personnel
					 routinely working with or around radiation sources shall not be required by the
					 registrant to restrain patients during CT examinations. If the procedure is
					 permitted personnel exposure shall not exceed the limits in R 333.5057 to R
					 333.5059 or the procedure is prohibited.
(5) When a patient must be held in position
					 for CT, mechanical supporting or restraining devices shall be used unless
					 contraindicated. If the patient is held by an individual, this individual shall
					 wear protective gloves and a protective apron of 0.5 millimeter minimum lead
					 equivalence and be so positioned that no part of his or her body is struck by
					 the useful beam and that his or her body is as far as possible from the edge of
					 the useful beam.
(6) Only
					 individuals whose presence is necessary are allowed in a fixed CT scanner room
					 during exposure. Each individual, except the patient, shall be protected by at
					 least 0.5 millimeter lead equivalent aprons or a whole body protective
					 barrier.
(7) Personnel monitoring
					 is required in controlled areas for each individual occupationally exposed to
					 ionizing radiation from CT scanner equipment. Individual monitoring devices
					 shall be permanently assigned to each occupationally exposed individual.
					 Monitoring shall be continuous during employment as a radiation
					 worker.
(8) Personnel exposure
					 records shall be kept on permanent available file at the facility where the
					 exposure occurs.
(9) Monitoring
					 devices used to estimate whole body exposure shall normally be worn on the
					 chest or abdomen. Monitoring of all other body parts shall meet the
					 requirements of R 333.5065.
(10)
					 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.
(11) A CT scanner
					 shall not be left unattended without locking the apparatus, room, or building
					 in some manner which prevents use of the apparatus by unauthorized
					 persons.
