Each licensee shall notify the Department , according to subsection (C), as
soon as possible, but not later than four hours after the discovery of an
event, and take immediate protective actions necessary to avoid exposures to
radiation or radioactive materials that could exceed the limits specified in
this Chapter or releases of licensed material that could exceed the limits
specified in this Chapter. For purposes of this Section, event means a
radiation accident involving a fire, explosion, gas release, or similar
occurrence.
B. Each licensee shall
notify the Department, according to subsection (C), within 24 hours after
discovering any of the following events involving licensed material:
1. A contamination event that:
a. Requires that anyone having access to the
contaminated area be restricted for more than 24 hours by the imposition of
additional radiological controls to prohibit entry into the area;
b. Involves a quantity of radioactive
material greater than five times the lowest annual limit on intake specified in
Appendix B of this Article; and
c.
Results in access to the contaminated area being restricted for a reason other
than to allow radionuclides with a half-life of less than 24 hours to decay
prior to decontamination.
2. An event in which equipment is disabled or
fails to function as designed when:
a. The
equipment is part of a system designed to prevent releases exceeding the limits
specified in this Chapter, to prevent exposures to radiation and radioactive
materials exceeding limits specified in this Chapter, or to mitigate the
consequences of an accident;
b. The
equipment performs a safety function; and
c. No redundant equipment is available and
operable to perform the required safety function.
3. An event that requires urgent medical
treatment of an individual with radioactive contamination on the individual's

and time;
3. The exact location of
the event;
4. The isotopes,
quantities, and chemical and physical form of the licensed material involved;
and
5. Any personnel radiation
exposure data available.
D. Each licensee who makes a report required
by subsection (A) or (B) shall submit to the Department a written follow-up
report within 30 days of the initial report. Written reports prepared as

of the event, including the probable cause and the manufacturer and model
number (if applicable) of any equipment that failed or malfunctioned;
2. The exact location of the event;
3. The isotopes, quantities, and chemical and
physical form of the licensed material involved;
4. Date and time of the event;
5. Corrective actions taken or planned and
the results of any evaluations or assessments; and
6. The extent of personnel exposure to
radiation or to radioactive materials without identification of each exposed
