Nev. Admin. Code § 459.329 - Requirements for planned special exposures
A licensee or registrant may permit a worker who is an adult to receive a planned special exposure, in addition to and accounted for separately from the doses received under the limits specified in NAC 459.325, if each of the following conditions is satisfied:
1. The licensee or registrant notifies the
Division of the planned special exposure in writing at least 10 working days
before the planned special exposure is scheduled to occur, and verifies that
the Division has received the letter of notification.
2. The planned special exposure is to occur
in an exceptional situation when alternatives that might avoid the higher
exposure are unavailable or impractical.
3. The licensee or registrant, and employer
if the employer is not the licensee or registrant, specifically authorizes the
planned special exposure, in writing, before the exposure occurs.
4. Before the planned special exposure, the
licensee or registrant ensures that each person involved is:
(a) Informed of the purpose of the planned
special exposure;
(b) Informed of
the estimated doses and associated potential risks, and the specific radiation
levels or other conditions that might be involved in performing the task;
and
(c) Instructed in the measures
to be taken to keep the dose as low as is reasonably achievable considering
other risks that may be present.
5. Before permitting a person to participate
in a planned special exposure, the licensee or registrant ascertains previous
doses received by the person during his or her lifetime as required pursuant to
NAC 459.365.
6. The planned special
exposure would not cause a person to receive a dose from all planned special
exposures and all doses in excess of:
(a) The
numerical values of any of the limits specified in subsection 1 of NAC 459.325
in any year; and
(b) Five times the
annual limits specified in subsection 1 of NAC 459.325 during the lifetime of
the person.
7. The
licensee or registrant maintains records of the conduct of the planned special
exposure in accordance with NAC 459.3655 and submits a written report in
accordance with NAC 459.3715.
8.
The licensee or registrant records the best estimate of the dose resulting from
the planned special exposure in the record of the person receiving the dose and
informs that person, in writing, of the dose within 30 days after the date of
the planned special exposure. The dose from planned special exposures must not
be considered in controlling the future occupational dose of the person
pursuant to subsection 1 of NAC 459.325, but must be included in the
determinations required to be made pursuant to subsections 5 and 6.
