Universal Citation: 180 NE Admin Rules and Regs ch 4 ยง 021

Current through September 17, 2024

Licensees and registrants must conduct surveys and monitor for radiation as follows.

021.01 AREA SURVEYS. Each licensee or registrant must make, or cause to be made, surveys of areas, including the subsurface, that:

(A) Are necessary for the licensee or registrant to comply with 180 NAC 4; and

(B) Are necessary under the circumstances to evaluate:
(i) The magnitude and extent of radiation levels; and

(ii) Concentrations or quantities of residual radioactivity; and

(iii) The potential radiological hazards of the radiation levels and residual radioactivity detected.

021.02 SUBSURFACE RESIDUAL RADIOACTIVITY. Despite the requirements of 180 NAC 4-048.01, records from surveys describing the location and amount of subsurface residual radioactivity identified at the site must be kept with records important for decommissioning, and those records must be retained in accordance with 180 NAC 3-018.07, as applicable.

021.03 SURVEY INSTRUMENT AND EQUIPMENT CALIBRATION. The licensee or registrant must ensure that instruments and equipment used for quantitative radiation measurements, including dose rate and effluent monitoring, are calibrated at intervals not to exceed 12 months for the radiation measured, except when a more frequent interval is specified in another applicable chapter or a license condition.

021.04 PERSONNEL DOSIMETERS. All personnel dosimeters, except for direct and indirect reading pocket ionization chambers and those dosimeters used to measure the dose to any extremity, that require processing to determine the radiation dose and that are used by licensees and registrants to comply with 180 NAC 4-005, with other applicable provisions of these regulations, or with conditions specified in a license or registration must be processed and evaluated by a dosimetry processor:

(A) Holding current personnel dosimetry accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology; and

(B) Approved in this accreditation process for the type of radiation or radiations included in the National Voluntary Laboratory Accreditation Program (NVLAP) program that most closely approximates the type of radiation or radiations for which the individual wearing the dosimeter is monitored.

021.05 DECEPTIVE EXPOSURE OF AN INDIVIDUAL MONITORING DEVICE. The licensee or registrant must ensure that adequate precautions are taken to prevent a deceptive exposure of an individual monitoring device.
