(1)

requires access to the contaminated area, by workers or the public, to be restricted for more than 24 hours by imposing additional radiological controls or by prohibiting entry into the areas;

(2)

involves a quantity of material greater than five times the lowest annual limit on intake specified in part 4731.2750 for the material; and


§
(3)

restricts access to the area for a reason other than to allow isotopes with a half-life of less than 24 hours to decay prior to decontamination;

an event in which equipment is disabled or fails to function as designed when:

§
(1)

the equipment is required by rule or license condition to prevent releases exceeding regulatory limits, to prevent exposure to radiation and radioactive materials exceeding regulatory limits, or to mitigate the consequences of an accident;
