RULE §336.310Planned Special Exposures

A licensee may authorize an adult worker to receive doses in addition to and accounted for separately from the doses received under the limits specified in §336.305 of this title (relating to Occupational Dose Limits for Adults) provided that each of the following conditions is satisfied:

  (1) The licensee authorizes a planned special exposure only in an exceptional situation when alternatives that might avoid the dose estimated to result from the planned special exposure are unavailable or impractical.

  (2) The licensee, and employer if the employer is not the licensee, specifically authorizes the planned special exposure, in writing, before the exposure occurs.

  (3) Before a planned special exposure, the licensee ensures that each individual involved is:

    (A) informed of the purpose of the planned operation; and

    (B) informed of the estimated doses and associated potential risks and 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.

  (4) Before permitting an individual to participate in a planned special exposure, the licensee ascertains prior doses as required by §336.309(b) of this title (relating to Determination of Prior Occupational Dose) during the lifetime of the individual for each individual involved.

  (5) Subject to §336.305(b) of this title, the licensee shall not authorize a planned special exposure that would cause an individual to receive a dose from all planned special exposures and all doses in excess of the limits to exceed:

    (A) the numerical values of any of the dose limits in §336.305(a) of this title in any year; and

    (B) five times the annual dose limits in §336.305(a) of this title during the individual's lifetime.

  (6) The licensee maintains records of the conduct of a planned special exposure in accordance with §336.345 of this title (relating to Records of Planned Special Exposures) and submits a written report to the executive director in accordance with §336.353 of this title (relating to Reports of Planned Special Exposures).

  (7) The licensee records the best estimate of the dose resulting from the planned special exposure in the individual's record and informs the individual, in writing, of the dose within 30 days from the date of the planned special exposure. The dose from planned special exposures shall not be considered in controlling future occupational dose of the individual under §336.305(a) of this title but shall be included in evaluations required by paragraphs (4) and (5) of this section.
