For a sealed source contained in a device, test samples are obtained when the source is in the "off" position. 6. The test for leakage for brachytherapy sources manufactured to contain radium shall be capable of detecting an absolute leakage rate of 37 Bq (0.001 µCi) of radon-222 in a twenty-four (24) hour period when the collection efficiency for radon-222 and its daughters has been determined with respect to collection method, volume and time. 7. Tests for contamination from radium daughters shall be taken on the interior surface of brachytherapy source storage containers and shall be capable of detecting the presence of 185 Bq (0.005 µCi) of a radium daughter which has a half-life greater than four (4) days. B. A licensee need not perform test for leakage or contamination on the following sealed sources: 1. Sealed sources containing only radioactive material with a half-life of less than thirty (30) days; 2. Sealed sources containing only radioactive material as a gas; 3. Sealed sources containing 3.7 MBq (100 µCi) or less of beta or photon-emitting material or 370 kBq (10 µCi) or less of alpha-emitting material; 4. Sealed sources containing only hydrogen-3; 5. Seeds of iridium-192 encased in nylon ribbon; and 6. Sealed sources, except teletherapy and brachytherapy sources, which are stored, not being used and identified as in storage. The licensee shall, however, test each such sealed source for leakage or contamination and receive the test results before any use or transfer unless it has been tested for leakage or contamination within six (6) months before the date of use or transfer. No sealed source shall be stored for a period of more than ten (10) years without being tested for leakage and/or contamination. C.

Immediately notify the Agency as soon as possible, but not later than four (4) hours after the discovery, of an event (e.g., fire, explosion, toxic gas release, etc.) that prevents immediate protective actions necessary to avoid exposures to radiation or radioactive materials that could exceed regulatory limits or releases of licensed material that could exceed regulatory limits. B. Twenty-Four Hour Notification. Each licensee or registrant shall, within twenty-four (24) hours of discovery of the event, report to the Agency each event involving loss of control of a licensed or registered source of radiation possessed by the licensee or registrant that may have caused, or threatens to cause, any of the following conditions: 1. An individual to receive, in a period of twenty-four (24) hours: a. A total effective dose equivalent exceeding 0.05 Sv (5 rem); or b. A lens dose equivalent exceeding 0.15 Sv (15 rem); or c. A shallow dose equivalent to the skin or extremities or a total organ dose equivalent exceeding 0.5 Sv (50 rem); or 2. The release of radioactive material, inside or outside of a restricted area, so that, had an individual been present for twenty-four (24) hours, the individual could have received an intake in excess of one occupational ALI. This provision does not apply to locations where personnel are not normally stationed during routine operations, such as hot-cells or process enclosures. 3. An unplanned contamination event that: a. Requires access to the contaminated area, by workers or the public, to be restricted for more than twenty-four (24) hours by imposing additional radiological controls or by prohibiting entry into the area; and b. Involves a quantity of material greater than five times the lowest annual limit on intake specified for the material in § 1.19 of this Part; and c. Has access to the area restricted for a reason other than to allow isotopes with a half-life of less than twenty-four (24) hours to decay prior to decontamination. 4. An event in which equipment is disabled or fails to function as designed when: a. The equipment is required by regulation or license/registration condition to prevent releases exceeding regulatory limits, to prevent exposures to radiation and/or radioactive materials exceeding regulatory limits, or to mitigate the consequences of an accident; and b. The equipment is required to be available and operable when it is disabled or fails to function; and c. No redundant equipment is available and operable to perform the required safety function. 5. An event that requires unplanned medical treatment at a medical facility of an individual with spreadable radioactive contamination on the individual's clothing or body. 6. An unplanned fire or explosion damaging any licensed material or any device, container, or equipment containing licensed material when: a. The quantity of material involved is greater than five (5) times the lowest annual limit on intake specified for the material in § 1.19 of this Part; and b. The damage affects the integrity of the licensed material or its container. C. The licensee or registrant shall prepare each report filed with the Agency pursuant to § 1.17.2 of this Part so that names of individuals who have received exposure to sources of radiation are stated in a separate and detachable portion of the report. D. Licensees or registrants shall make the reports required by §§ 1.17.2(A) and (B) of this Part to the Agency by telephone, telegram, mailgram, or facsimile to the Agency. To the extent that the information is available at the time of notification, the information provided in these reports shall include: 1. The name of the person making the report and their call-back telephone number; 2. A description of the event, including time and date; 3. The exact location of the event; 4. The levels of radiation and the isotopes, quantities, and chemical and physical form of the licensed material involved; and 5. Any personnel radiation exposure data available. E. The provisions of § 1.17.2 of this Part do not apply to doses that result from planned special exposures, provided such doses are within the limits for planned special exposures and are reported pursuant to § 1.17.4 of this Part. 1.17.3 Reports of Exposures, Radiation Levels, and Concentrations of Radioactive Material Exceeding the Constraints or Limits For the purpose of this Part, requirements regarding reports of exposures, radiation levels, and concentrations of radioactive material exceeding the constraints or limits are defined by 10 C.F.R. § 20.2203, excluding 10 C.F.R. § 20.2203(c). 1.17.4 Reports of Planned Special Exposures For the purpose of this Part, requirements regarding reports of planned special exposures are defined by 10 C.F.R. § 20.2204. 1.17.5 Notifications and Reports to Individuals When a licensee or registrant is required pursuant to §§ 1.17.3 or 1.17.4 of this Part to report to the Agency any exposure of an individual to radiation or radioactive material, the licensee or registrant shall also notify the individual. Such notice shall be transmitted at a time not later than the transmittal to the Agency. 1.17.6 Reports of Transactions Involving Nationally Tracked Sources For the purpose of this Part, requirements regarding reports of transactions involving nationally tracked sources are defined by 10 C.F.R. § 20.2207. 1.17.7 Vacating Premises Each specific licensee shall, no less than thirty (30) days before vacating or relinquishing possession or control of premises which may have been contaminated with radioactive material as a result of his or her activities, notify the Agency in writing of intent to vacate. When deemed necessary by the Agency, the licensee shall decontaminate the premises in such a manner as the Agency may specify. 1.18 Assigned Protection Factors for Respirators For the purpose of this Part, assigned protection factors for respirators are defined in Appendix A to 10 C.F.R. Part 20. 1.19 Annual Limits on Intake (ALIs) and Derived Air Concentrations (DACs) of Radionuclides for Occupational Exposure; Effluent Concentrations; Concentrations for Release to Sewerage For the purpose of this Part, Annual Limits on Intake (ALIs) and Derived Air Concentrations (DACs) of radionuclides for occupational exposure; effluent concentrations; and concentrations for release to sewerage are defined in Appendix B to 10 C.F.R. Part 20. 1.20 Quantities of Licensed Material Requiring Labeling For the purpose of this Part, quantities of licensed material requiring labeling are defined in Appendix C to 10 C.F.R.
