Arizona Administrative Code
Section R9-7-418 - Surveys and Monitoring

Universal Citation: AZ Admin Code R 9-7-418

Current through Register Vol. 30, No. 12, March 22, 2024

A. Each licensee or registrant shall make, or cause to be made, surveys if surveys are:

1. Necessary for the licensee or registrant to comply with Article 4, and

2. Reasonable under the circumstances to evaluate:
a. The magnitude and extent of radiation levels, and

b. Concentrations or quantities of residual radioactivity, and

c. The potential radiological hazards of the radiation levels and residual radioactivity detected.

B. 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 R9-7-408, with other applicable provisions of these rules, or with conditions specified in a license or registration shall be processed and evaluated by a dosimetry processor:

1. Holding current personnel dosimetry accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology, according to NVLAP procedures published March 1994 as NIST Handbook 150, and NIST Handbook 150-4, published August 1994, which is incorporated by reference, published by the U.S. Government Printing Office, Washington D.C. 20402-9325, and on file with the Department. The material incorporated by reference contains no future editions or amendments;

2. Approved in this accreditation process for the type of radiation or radiations included in the NVLAP program that most closely approximates the type of radiation or radiations for which the individual wearing the dosimeter is monitored; and

3. Film badges must be replaced at periods not to exceed one month; other personnel dosimeters processed and evaluated by an accredited NVLAP processor must be replaced at periods not to exceed three months.

C. The licensee or registrant shall ensure that adequate precautions are taken to prevent a deceptive exposure of an individual monitoring device and that personnel monitoring devices are issued to, and used by only the individual to whom the monitoring device has been first issued during any reporting period.

D. A licensee shall ensure that survey instruments and personnel dosimeters that are used to make quantitative measurements are calibrated in accordance with R9-7-449.

E. Records.

1. Each licensee or registrant shall maintain records showing the results of surveys required by this Section and R9-7-433(B). The licensee or registrant shall retain these records for three years after the record is made.

2. The licensee or registrant shall retain each of the following records for three years after the Department terminates the license or registration:
a. Records of the survey results used to determine the dose from external sources of radiation, in the absence of or in combination with individual monitoring data, and provide an assessment of individual dose equivalents;

b. Records of the results of measurements and calculations used to determine individual intakes of radioactive material and to assess an internal dose;

c. Records showing the results of air sampling, surveys, and bioassays required according to R9-7-425(A)(3)(a) and (b);

d. Records of the measurement and calculation results used to evaluate the release of radioactive effluents to the environment; and

e. Notwithstanding subsection (A) 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 R9-7-323, as applicable.
