Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Radiographic operations using sealed sources
						shall not be performed unless, at all times during radiographic operations, all
						radiographic personnel wear, on the trunk of the body, a direct reading pocket
						dosimeter, an operating alarm ratemeter, and a personnel dosimeter except that at
						permanent radiographic installations, the wearing of an alarming ratemeter is not
						required. Each personnel dosimeter shall be assigned to and worn by only one
						individual.
(b) Film badges shall be
						replaced at periods not to exceed one month and all other personnel dosimeters that
						require replacement shall be replaced at periods not to exceed three months. All
						personnel dosimeters shall be evaluated at least quarterly or promptly after
						replacement, whichever is more frequent.
(c) Pocket dosimeters shall have a range from zero
						to 200 millirems and be recharged at the start of each shift. Electronic personal
						dosimeters may only be used in place of ion-chamber pocket dosimeters.
(d) Pocket or electronic personal dosimeters shall
						be read and exposures recorded at the beginning and end of each shift. A record of
						these exposures shall be retained for three years after the record is made and
						indicate, for each dosimeter used, the manufacturers name, model and serial number
						and name of individual to whom assigned.
(e) Pocket and electronic personal dosimeters
						shall be checked at periods not to exceed one year for correct response to radiation
						and shall read within plus or minus 20 percent of the true radiation exposure. A
						record of these exposures shall be retained for three years after the record is made
						and indicate, for each dosimeter used, the manufacturers name, model and serial
						number.
(f) If an individual's pocket
						dosimeter is found to be discharged beyond its range or if the individual's
						electronic personal dosimeter reads greater than 200 millirems and the possibility
						of radiation exposure cannot be ruled out as the cause, the individual's personnel
						dosimeter shall be sent for processing and evaluation within 24 hours. For personnel
						dosimeters that do not require processing, evaluation of the dosimeter shall be
						started within 24 hours. The individual may not resume work associated with any
						source of radiation until the individual's radiation dose has been determined. The
						user's radiation safety officer or his designee shall make this determination and
						the results shall be kept available for inspection and maintained until the
						Department terminates the license.
(g)
						Personnel dosimeter results shall be maintained until the Department terminates the
						license.
(h) Each alarming ratemeter
						shall:
(1) Be checked to ensure that the alarm
						functions properly (sounds) prior to use at the start of each shift;
(2) Be set to give an alarm signal at a preset
						dose rate of 500 millirems per hour;
(3)
						Require special means to change the preset alarm function;
(4) Be calibrated at periods not to exceed one
						year for correct response to radiation; and
(5) Alarm within plus or minus 20 percent of the
						true radiation dose rate.
