Radiation Exposure Records and Reports

PURPOSE: This rule requires the user of radiation sources to keep records of personnel exposures, radiation measurements and the receipt and disposal of radioactive materials. It also states the conditions under which personnel exposures and radiation incidents must be reported. (1) Records of all measurements required by 19 CSR 20-10.050 shall be kept available by the user for inspection by a representative of the department. Personnel monitoring records shall include the Social Security number and date of birth of the individual concerned. (2) An accurate accounting for all radioactive materials, not specifically exempted by 19 CSR 20-10.020, shall be maintained. The records shall show the amount of radioactive material received, transferred, decayed in storage and disposed of and other information as may be necessary to account for the difference between the amount of radioactive material received or produced and the amount on hand. The user shall also keep records of the release of radioactive materials to the environs sufficient to demonstrate compliance with other rules of this chapter. The records shall be maintained and made available for inspection for at least five (5) years after final disposition of the radioactive material. (3) Upon termination of employment of an individual, the individual or department, or both, upon request, shall be supplied with a summary statement of that individual’s radiation dose. (The estimated maximum dose shall be stated if no personnel monitoring has been carried out.) This record shall include statements of any circumstances where the dose to the employee from any source of radiation exceeded those specified in this chapter. Employee records must be kept available for inspection by the department during the tenure of employment of an employee and for a period of five (5) years after that. (4) When it is known or believed that an accidental dose to a person in the installation may have exceeded two (2) times the amount permitted by applicable sections of 19 CSR2010.040, all facts relative to the occurrence shall be reported in detail to the department within seven (7) days of the discovery of the facts, and a copy of the report shall be put in that individual’s personnel file. The cause of the overexposure shall immediately be sought out and corrected. (5) The loss or theft of any source of radiation not exempt from these rules shall be reported immediately to the department by telephone and a written report shall be submitted within twenty-four (24) hours. (6) At the request of any employee, each user shall advise the employee annually of the employee’s exposure to radiation as shown in records maintained by the user. (7) Any accident involving either a public or private carrier conveying radioactive material shall be reported immediately to the Department of Health by telephone and a written report shall be submitted within twenty-four (24) hours.
