NAC459.329. 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.
