      1. a. A total effective dose equivalent exceeding five one hundredths (0.05) Sv (five (5) rem); or
      2. b. A lens dose equivalent exceeding fifteen one hundredths (0.15) Sv (fifteen (15) rem); or
      3. c. A shallow dose equivalent to the skin or extremities or a total organ dose equivalent exceeding one half (0.5) Sv (fifty (50) rem); or
   2. 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 (1) 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. 3. An unplanned contamination event that:

      1. 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
      2. b. Involves a quantity of material greater than five (5) times the lowest annual limit on intake specified for the material in § 1.19 of this Part; and
      3. 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. 4. An event in which equipment is disabled or fails to function as designed when:

      1. 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
      2. b. The equipment is required to be available and operable when it is disabled or fails to function; and
