Notification of Incidents

(A) Immediate Notification. Notwithstanding any other requirements for notification, each licensee or registrant shall immediately report each event involving a 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: (a) a total effective dose equivalent of 0.25 sievert (25 rems) or more; (b) a lens dose equivalent of 0.75 sievert (75 rems) or more; (c) a shallow dose equivalent to the skin or extremities or a total organ dose equivalent of 2.5 grays (250 rads) or more; or (2) The release of radioactive material, inside or outside of a restricted area, so that, had an individual been present for 24 hours, the individual could have received an intake five times the 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. (B) 24 Hour Notification. Each licensee or registrant shall, within 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 24 hours: (a) a total effective dose equivalent exceeding 0.05 sievert (five rems); (b) a lens dose equivalent exceeding 0.15 sievert (15 rems); (c) a shallow dose equivalent to the skin or extremities or a total organ dose equivalent exceeding 0.5 sievert (50 rems); or (2) The release of radioactive material, inside or outside of a restricted area, so that, had an individual been present for 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. (C) Licensees or registrants shall make the reports required by 105 CMR 120.282(A) and (B) by initial contact by telephone to the Agency and shall confirm the initial contact by telegram, mailgram, or facsimile to the Agency. (D) The licensee or registrant shall prepare each report filed with the Agency pursuant to 105 CMR 120.282 so that names of individuals who have received exposure to sources of radiation are stated in a separate and detachable portion of the report. (E) The provisions of 105 CMR 120.282 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 105 CMR 120.284.
