HAR §11-45-44. Determination of prior occupational dose

(a) For each individual who may enter the licensee's restricted or controlled area and is likely to receive, in a year, an occupational dose requiring monitoring pursuant to section 11-45- 54, the licensee shall: (1) Determine the occupational radiation dose received during the current year; and (2) Attempt to obtain the records of lifetime cumulative occupational radiation dose. (b) Before 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 subsection (a), 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 received during the current year; and (2) Accept, as the record of lifetime cumulative radiation dose, an up-to-date department 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 licensee; 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, by telephone, telegram, facsimile, 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, as required by subsection (a), on a form provided by the department, or other clear and legible record, of all the information required on that form. 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 obtains reports, the licensee shall use the dose shown in the report in preparing the department form. For any period in which the licensee does not obtain a report, the licensee shall place a notation on the department form indicating the periods of time for which data are not available. Licensees are not required to reevaluate the separate external dose equivalents and internal §11-45-45 45-55 committed dose equivalents or intakes of radionuclides assessed before the effective date of these rules. Further, occupational exposure histories obtained and recorded on the department form before the effective date of these rules, 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. (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 section 11-45-40(f). for the current year, that the allowable dose limit for the individual is reduced by 1.25 rems (12.5 millisieverts) 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 records until the department terminates each pertinent license requiring this record.
