For each individual who is likely to receive in a year, an occupational dose requiring monitoring according to part 4732.0440, the registrant must:
determine the occupational radiation dose received during the current year; and
attempt to obtain the records of the cumulative occupational radiation dose.
A registrant may:
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 amount of any occupational dose that the individual received; or
accept as the record of cumulative radiation dose, an up-to-date form, 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 registrant.
The registrant must record all the required history in a legible record.
If the registrant is unable to obtain a complete record of an individual's current and previously accumulated occupational dose, the registrant must assume:
the allowable dose limits for the individual is reduced by 1.25 rem (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
that the individual is not available for planned special exposures.
