Section 30333.2 - Personnel Monitoring Control(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.(i) Alarming ratemeter calibration records shall be maintained for three years.(j) If the personnel dosimeter that is required by subsection (a) is lost or damaged during radiographic operations, the worker shall cease work immediately until a replacement personnel dosimeter is provided and the exposure is calculated for the time period from issuance to loss or damage of the personnel dosimeter. The radiation safety officer shall perform the calculation. The results with measurements, calculated data, and assumptions made to obtain the calculated exposure and the time period for which the personnel dosimeter was lost or damaged shall be maintained until the Department terminates the license.Cal.
