Section R9-7-412 - Determination of Prior Occupational Dose

1. Determine the occupational radiation dose received during the current year, and

2. Attempt to obtain the records of lifetime cumulative occupational radiation dose.

1. The internal and external doses from all previous planned special exposures; and

2. All doses in excess of the limits received during the lifetime of the individual, including doses received during accidents and emergencies; and

3. All lifetime, cumulative, occupational radiation doses.

1. Accept, as a record of the occupational dose that the individual received during the current year, a written and 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 received during the current year; and

2. Accept, as the record of lifetime cumulative radiation dose, an up-to-date Department Form Y (available from the Department) 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 or registrant; and

3. Obtain reports of the individual's dose equivalent 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 or registrant, by telephone, telegram, facsimile, or letter. The licensee or registrant shall request a written verification of the dose data if the authenticity of the transmitted report cannot be established.

1. The licensee or registrant shall record the exposure history, as required by subsection (A), on Department Form Y (available from the Department) or a similar clear and legible record of all the information required by this subsection. The form or record shall show each period in which the individual received occupational exposure to radiation or radioactive material and shall be signed by the individual who received the exposure. For each period for which the licensee or registrant obtains reports, the licensee or registrant shall use the dose shown in the report for preparing Department Form Y or its equivalent. For any period in which the licensee or registrant does not obtain a report, the licensee or registrant shall place a notation on Department Form Y or its equivalent indicating each period of time for which there is no data.

2. The licensee or registrant is not required to reevaluate the separate external dose equivalents and internal committed dose equivalents or intakes of radionuclides assessed according to the rules in Article 4 in effect before January 1, 1994. Occupational exposure histories obtained and recorded on Department Form Y or its equivalent before January 1, 1994, would not have included effective dose equivalent but may be used in the absence of specific information on the intake of radionuclides by the individual.

3. If the licensee or registrant is unable to obtain a complete record of an individual's current and previously accumulated occupational dose, the licensee or registrant shall:

4. The licensee or registrant shall retain current and prior records on Department Form Y or its equivalent for three years after the Department terminates each pertinent license or registration requiring this record. The licensee or registrant shall retain records used in preparing Department Form Y or its equivalent for three years after the record is made.
