Sec.  835.204  Planned special exposures.

    (a) A planned special exposure may be authorized for a radiological 
worker to receive doses in addition to and accounted for separately from 
the doses received under the limits specified in

[[Page 541]]

Sec.  835.202(a), provided that each of the following conditions is 
satisfied:
    (1) The planned special exposure is considered only in an 
exceptional situation when alternatives that might prevent a 
radiological worker from exceeding the limits in Sec.  835.202(a) are 
unavailable or impractical;
    (2) The contractor management (and employer, if the employer is not 
the contractor) specifically requests the planned special exposure, in 
writing; and
    (3) Joint written approval is received from the appropriate DOE 
Headquarters program office and the Secretarial Officer responsible for 
environment, safety and health matters.
    (b) Prior to requesting an individual to participate in an 
authorized planned special exposure, the individual's dose from all 
previous planned special exposures and all doses in excess of the 
occupational dose limits shall be determined.
    (c) An individual shall not receive a planned special exposure that, 
in addition to the doses determined in Sec.  835.204(b), would result in 
a dose exceeding the following:
    (1) In a year, the numerical values of the dose limits established 
at Sec.  835.202(a); and
    (2) Over the individual's lifetime, five times the numerical values 
of the dose limits established at Sec.  835.202(a).
    (d) Prior to a planned special exposure, written consent shall be 
obtained from each individual involved. Each such written consent shall 
include:
    (1) The purpose of the planned operations and procedures to be used;
    (2) The estimated doses and associated potential risks and specific 
radiological conditions and other hazards which might be involved in 
performing the task; and
    (3) Instructions on the measures to be taken to keep the dose ALARA 
considering other risks that may be present.
    (e) Records of the conduct of a planned special exposure shall be 
maintained and a written report submitted within 30 days after the 
planned special exposure to the approving organizations identified in 
Sec.  835.204(a)(3).
    (f) The dose from planned special exposures is not to be considered 
in controlling future occupational dose of the individual under Sec.  
835.202(a), but is to be included in records and reports required under 
this part.
