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.

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.
