Fla. Admin. Code R. 64E-5.308

Current through Reg. 50, No. 235-239, December 10, 2024

Section 64E-5.308 - Determination of Prior Occupational Dose

(1) For each individual who is likely to receive in a year an occupational dose requiring monitoring as specified in Rule 64E-5.315, F.A.C., the licensee or registrant shall:

(a) Determine the occupational radiation dose received during the current year; and,

(b) Attempt to obtain the records of lifetime cumulative occupational radiation dose.

(2) Prior to permitting an individual to participate in a planned special exposure, the licensee or registrant shall determine:

(a) The internal and external doses from all previous planned special exposures;

(b) All doses in excess of the limits received during the lifetime of the individual, including doses received during accidents and emergencies; and,

(c) All lifetime cumulative occupational radiation doses.

(3) In complying with the requirements of subsection 64E-5.308(1), F.A.C., a licensee or registrant can:

(a) Accept 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 as a record of the occupational dose that the individual received during the current year;

(b) Accept an up-to-date DOH Form 1623 July 1993, which is herein incorporated by reference and which is available from the department, or an 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 as the record of lifetime cumulative radiation dose; and,

(c) 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.

(4) The licensee or registrant shall record the exposure history, as required by subsection 64E-5.308(1), F.A.C., on DOH Form 1623 July 1993 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 or registrant obtains reports, the licensee or registrant shall use the dose shown in the report in preparing DOH Form 1623 July 1993 or equivalent. For any period in which the licensee or registrant does not obtain a report, the licensee or registrant shall place a notation on DOH Form 1623 July 1993 or equivalent indicating the periods of time for which data are not available.

(5) Licensees are not required to reevaluate the separate external dose equivalents and internal committed dose equivalents or intakes of radionuclides assessed as specified in the rules in this part in effect before the effective date of this rule. Further, occupational exposure histories obtained and recorded on DOH Form 1623 or equivalent before the effective date of this rule would not have included effective dose equivalents, but can be used in the absence of specific information on the intake of radionuclides by the individual.

(6) 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 assume:

(a) That the allowable dose limit for the individual is reduced by 1.25 rem (12.5 millisievert) for each quarter for which records were unavailable and the individual was engaged in activities that could have resulted in occupational radiation exposure to establish administrative controls as specified in subsection 64E-5.304(6), F.A.C., for the current year; and,

(b) That the individual is not available for planned special exposures.

(7) The licensee or registrant shall retain the records on DOH Form 1623 July 1993 or equivalent until the department terminates each pertinent license or registration requiring this record. The licensee or registrant shall retain records used in preparing DOH Form 1623 July 1993 or equivalent for 3 years after the record is made.
