HAR §11-45-108. Personnel monitoring control

(a) The licensee shall not permit any individual to act as a radiographer or as a radiographer trainee unless, at all times during radiographic operations, the individual wears a direct reading pocket dosimeter, an alarm ratemeter, and either a film badge or a thermoluminescent dosimeter (TLD). Pocket dosimeters shall have a range from zero to two hundred milliroentgens (5.16 x 10-5 coulombs per kilogram) and shall be recharged daily or at the start of each shift. Each film badge or TLD shall be assigned to and worn by only one individual. (b) Pocket dosimeters shall be read and exposures recorded at least once daily. (c) Pocket dosimeters shall be checked for correct response to radiation at periods not to exceed one year. Acceptable dosimeters shall read within plus or minus thirty percent of the true radiation exposure. Records of this check shall be maintained for inspection by the department for three years. (d) Each alarm ratemeter shall: (1) Be checked to ensure that the alarm functions properly §11-45-108 45-84 (sounds) before use at the start of each shift; (2) Be set to give an alarm signal at a preset dose rate of five hundred milliroentgens per hour; (3) Require special means to change the preset alarm function; and (4) Be calibrated at periods not to exceed one year for correct response to radiation. Acceptable ratemeters shall alarm within plus or minus twenty percent of the true radiation dose rate. Records of these calibrations shall be maintained for inspection by the department for three years. (e) If an individual's pocket dosimeter is inoperable or discharged beyond its range, industrial radiographic operations by that individual shall cease and the individual's film badge or TLD shall be processed immediately. The individual shall not return to work with x-ray systems until a determination of the radiation exposure has been made. (f) Reports received from the film badge or TLD processor and records of daily pocket dosimeter readings shall be kept for inspection by the department for three years. (g) If a film badge or TLD is lost or damaged, the worker shall cease work immediately until a replacement film badge or TLD is provided and the exposure is calculated for the time period from issuance to loss or damage of the film badge or TLD.
