Iowa Code r. 641-40.36 - Surveys and monitoring-general
(1)
Each licensee or 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 this chapter;
and
b. Are necessary under the
circumstances to evaluate:
(1) The magnitude
and extent of radiation levels; and
(2) Concentrations or quantities of residual
radioactivity; and
(3) The
potential radiological hazards of the radiation levels and residual
radioactivity detected.
(2) Notwithstanding
641-40.82 (136C), 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 641-subrule 39.4(26) as
applicable.
(3) The licensee or
registrant shall ensure that instruments and equipment used for quantitative
radiation measurements, for example, 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 part of
these rules or a license condition.
(4) 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 641-40.15 (136C), 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:
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 NVLAP program that most
closely approximates the type of radiation or radiations for which the
individual wearing the dosimeter is monitored.
(5) The licensee or registrant shall ensure
that adequate precautions are taken to prevent a deceptive exposure of an
individual monitoring device.
(6)
After replacement, each personnel dosimeter must be sent for processing as soon
as possible.
