Current through Register Vol. 30, No. 38, September 20, 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.
