Nev. Admin. Code § 459.337 - Surveys and monitoring

1. Each licensee and registrant shall make, or cause to be made, surveys of areas, including the subsurface, that:

(a) Are necessary for the licensee or registrant to comply with NAC 459.010 to 459.950, inclusive, and sections 5 to 12, inclusive, of this regulation; and

(b) Are necessary under the circumstances to evaluate:

(1) The magnitude and extent of radiation levels;

(2) Concentrations or quantities of residual radioactivity; and

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

2. The Division shall evaluate surveys of areas made by a licensee or registrant pursuant to subsection 1 to determine if a significant risk to public health and safety exists. The Division may require the licensee or registrant to make an additional survey of areas if:

(a) The conditions under which the previous survey was made have changed; and

(b) The Division determines that the change in conditions described in paragraph (a) may result in a significant risk to public health and safety.

3. Records from surveys describing the location and amount of subsurface residual radioactivity identified at a site must be:

(a) Kept with records important to the decommissioning of a facility; and

(b) Retained in accordance with the provisions of subsection 13 of NAC 459.1955.

4. The licensee or registrant shall ensure that instruments and equipment used for quantitative radiation measurements are calibrated for the radiation measured at intervals not to exceed 12 months.

5. 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 dose of radiation and that are used by licensees and registrants to comply with NAC 459.325, with other applicable provisions of NAC 459.010 to 459.950, inclusive , and sections 5 to 12, inclusive, of this regulation, or with conditions specified in a license or registration, must be processed and evaluated by a dosimetry processor who is accredited by the National Voluntary Laboratory Accreditation Program of the National Institute of Standards and Technology for the type of radiation or radiations included in the program that most closely approximate the type of radiation for which the person wearing the dosimeter is monitored.

6. The licensee or registrant shall ensure that adequate precautions are taken to prevent a deceptive exposure of personnel monitoring equipment.
