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

   1. (1) may be necessary to demonstrate compliance with this part; and

   2. (2) are necessary under the circumstances to evaluate:

      1. (a) the magnitude and extent of radiation levels;
      2. (b) concentrations or quantities of radioactive material and residual radioactivity;

      3. (c) the potential radiological hazards of the radiation levels and residual

         radioactivity detected; and

      4. (d) notwithstanding 10 CFR 20 or equivalent state regulations of this part, 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 such records must be retained in accordance with the applicable regulations in 10 CFR parts 30, 40, 50, 70, or 72.30 or equivalent state regulations.

2. B. The licensee or registrant shall ensure that instruments and equipment used for quantitative radiation measurements (e.g. dose rate and effluent monitoring) are calibrated at intervals not to exceed 12 months, except when a more frequent interval is specified in another applicable part of this chapter or in a license condition.

3. C. All personnel dosimeters (except for direct and indirect reading pocket ionization chambers and those dosimeters used to measure the dose to the extremity) that require processing to determine the radiation dose and that are used by licensees and registrants to comply with 20.3.4.405 NMAC, with other applicable provisions of this chapter or with conditions specified in a license or registration shall be processed and evaluated by a dosimetry processor:

   1. (1) holding current personnel dosimetry accreditation from the national voluntary laboratory accreditation program (NVLAP) of the national institute of standards and technology (NIST); and
   2. (2) 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.
4. D. The licensee or registrant shall ensure that adequate precautions are taken to prevent a deceptive exposure of an individual monitoring device.
