                   Subpart C--Occupational Dose Limits
 
Sec. 20.1206  Planned 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 Sec. 20.1201 provided that each of the 
following conditions is satisfied--
    (a) 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.
    (b) The licensee (and employer if the employer is not the licensee) 
specifically authorizes the planned special exposure, in writing, before 
the exposure occurs.
    (c) Before a planned special exposure, the licensee ensures that the 
individuals involved are--
    (1) Informed of the purpose of the planned operation;
    (2) 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
    (3) Instructed in the measures to be taken to keep the dose ALARA 
considering other risks that may be present.
    (d) Prior to permitting an individual to participate in a planned 
special exposure, the licensee ascertains prior doses as required by 
Sec. 20.2104(b) during the lifetime of the individual for each 
individual involved.
    (e) Subject to Sec. 20.1201(b), the licensee does 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--
    (1) The numerical values of any of the dose limits in Sec. 
20.1201(a) in any year; and
    (2) Five times the annual dose limits in Sec. 20.1201(a) during the 
individual's lifetime.
    (f) The licensee maintains records of the conduct of a planned 
special exposure in accordance with Sec. 20.2105 and submits a written 
report in accordance with Sec. 20.2204.
    (g) 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 is 
not to be considered in controlling future occupational dose of the 
individual under Sec. 20.1201(a) but is to be included in evaluations 
required by Sec. 20.1206 (d) and (e).
