a)
Immediate Notification. Notwithstanding any other requirements for
notification, each licensee or registrant shall immediately report to the
Agency discovery of an event that prevents immediate protective actions
necessary to avoid releases of radioactive material or doses in excess of the
regulatory limits, or 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 Sv (25 rem) or more; or
B)
A lens dose equivalent of 0.75 Sv (75 rem) or more; or
C) A shallow dose equivalent to the skin or
extremities or a total organ dose equivalent of 2.5 Gy (250 rad) 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 ALI, except the provisions of this subsection (a) do 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 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 24 hours, the individual could have received an
intake in excess of one occupational ALI, except the provisions of this
subsection (b) do not apply to locations where personnel are not normally
stationed during routine operations, such as hot cells or process
enclosures.
c) Additional
24 Hour Notifications for Licensees. Each licensee shall notify the Agency
within 24 hours after the discovery of any of the following events involving
radioactive material:
1) An unplanned
contamination event that:
A) Requires access
to the contaminated area by workers or the public to be restricted for more
than 24 hours by imposing radiological controls in addition to those
established by the licensee prior to the event or by prohibiting entry into the
area;
B) Involves a quantity of
material greater than five times the lowest annual limit on intake specified in
10 CFR 20, appendix B, published at 72 Fed. Reg. 55922, October 1, 2007, for
the material; and
C) Results in
access to the area being restricted for a reason other than to comply with
operating procedures established by the licensee or 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 designated when:
A) The equipment is required by regulation or
license condition to prevent releases or doses exceeding regulatory limits, or
to mitigate the consequences of an accident;
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.
3) An event that requires unplanned medical
treatment at a medical facility of an individual with radioactive contamination
on the individual's clothing or body.
4) 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 times the lowest annual limit on intake
specified in 10 CFR 20, appendix B, published at 72 Fed. Reg. 55922, October 1,
2007, for the material; and
B) The
damage affects the integrity of the licensed material or its
container.
d)
Licensees or registrants shall make the reports required by subsections (a)
through (c) by initial contact by telephone to the Agency at (217) 782-7860 and
shall confirm the initial contact within 24 hours by overnight letter or
telefacsimile to the Agency.
e) The
licensee or registrant shall prepare each written report filed with the Agency
pursuant to this Section so that names of individuals who have received
exposure to sources of radiation are stated in a separate and detachable
portion of the report.
f) The
provisions of this Section 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 Section
340.1240.
