[56 FR 23404, May 21, 1991, as amended at 60 FR 20185, Apr. 25, 1995; 66 FR 64737, Dec. 14, 2001] (a) For each individual who is likely to receive in a year, an occupational dose requiring monitoring pursuant to §20.1502 the licensee shall— (1) Determine the occupational radiation dose received during the current year; and (2) Attempt to obtain the records of cumulative occupational radiation dose. (b) Prior to permitting an individual to participate in a planned special exposure, the licensee shall determine— (1) The internal and external doses from all previous planned special exposures; and (2) All doses in excess of the limits (including doses received during accidents and emergencies) received during the lifetime of the individual. (c) In complying with the requirements of paragraph (a) of this section, a licensee may— (1) Accept, as a record of the occupational dose that the individual received during the current year, a written signed statement from the individual, or from the individual's most recent employer for work involving radiation exposure, that discloses the nature and the amount of any occupational dose that the individual may have received during the current year; (2) Accept, as the record of cumulative radiation dose, an up-to-date NRC Form 4, or equivalent, signed by the individual and countersigned by an appropriate official of the most recent employer for work involving radiation exposure, or the individual's current employer (if the individual is not employed by the licensee); and (3) Obtain reports of the individual's dose equivalent(s) from the most recent employer for work involving radiation exposure, or the individual's current employer (if the individual is not employed by the licensee) by telephone, telegram, electronic media, or letter. The licensee shall request a written verification of the dose data if the authenticity of the transmitted report cannot be established. (d) The licensee shall record the exposure history of each individual, as required by paragraph (a) of this section, on NRC Form 4, or other clear and legible record, including all of the information required by NRC Form 44 4 Licensees are not required to partition historical dose between external dose equivalent(s) and internal committed dose equivalent(s). Further, occupational exposure histories obtained and recorded on NRC Form 4 before January 1, 1994, might not have included effective dose equivalent, but may be used in the absence of specific information on the intake of radionuclides by the individual. (e) If the licensee is unable to obtain a complete record of an individual's current and previously accumulated occupational dose, the licensee shall assume— (1) In establishing administrative controls under §20.1201(f) for the current year, that the allowable dose limit for the individual is reduced by 1.25 rems (12.5 mSv) for each quarter for which records were unavailable and the individual was engaged in activities that could have resulted in occupational radiation exposure; and (2) That the individual is not available for planned special exposures. (f) The licensee shall retain the records on NRC Form 4 or equivalent until the Commission terminates each pertinent license requiring this record. The licensee shall retain records used in preparing NRC Form 4 for 3 years after the record is made. This includes records required under the standards for protection against radiation in effect prior to January 1, 1994. [56 FR 23404, May 21, 1991, as amended at 57 FR 57878, Dec. 8, 1992; 60 FR 20186, Apr. 25, 1995; 60 FR 36043, July 13, 1995] (a) For each use of the provisions of §20.1206 for planned special exposures, the licensee shall maintain records that describe— (1) The exceptional circumstances requiring the use of a planned special exposure; and (2) The name of the management official who authorized the planned special exposure and a copy of the signed authorization; and (3) What actions were necessary; and (4) Why the actions were necessary; and (5) How doses were maintained ALARA; and (6) What individual and collective doses were expected to result, and the doses actually received in the planned special exposure. (b) The licensee shall retain the records until the Commission terminates each pertinent license requiring these records. (a) Recordkeeping requirement. Each licensee shall maintain records of doses received by all individuals for whom monitoring was required pursuant to §20.1502, and records of doses received during planned special exposures, accidents, and emergency conditions. These records5 5 Assessments of dose equivalent and records made using units in effect before the licensee's adoption of this part need not be changed. (1) The deep-dose equivalent to the whole body, lens dose equivalent, shallow-dose equivalent to the skin, and shallow-dose equivalent to the extremities; (2) The estimated intake of radionuclides (see §20.1202); (3) The committed effective dose equivalent assigned to the intake of radionuclides; (4) The specific information used to assess the committed effective dose equivalent pursuant to §20.1204 (a) and (c), and when required by §20.1502; (5) The total effective dose equivalent when required by §20.1202; and (6) The total of the deep-dose equivalent and the committed dose to the organ receiving the highest total dose.
