Current through Register Vol. 47, No. 6, September 18, 2024
(1)
Immediate notification. Notwithstanding other requirements for notification,
each licensee or registrant shall immediately report 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:
a. An individual to receive:
(1) A total effective dose equivalent of 25
rem (0.25 Sv) or more; or
(2) A
lens dose equivalent of 75 rem (0.75 Sv) or more; or
(3) A shallow dose equivalent to the skin or
extremities of 250 rad (2.5 Gy) or more; or
b. 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
annual limit on intake. This provision does not apply to locations where
personnel are not normally stationed during routine operations, such as
hot-cells or process enclosures.
c.
In addition to the requirements of paragraphs"a "
and"b " above, each licensee shall notify the Iowa department
of public health as soon as possible but not later than four hours after the
discovery of an event that prevents immediate protective actions necessary to
avoid exposures to radiation or radioactive materials that could exceed
regulatory limits or releases of licensed material that could exceed regulatory
limits (events may include fires, explosions, toxic gas releases, and other
such events).
(2)
Twenty-four-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:
a. An individual to
receive, in a period of 24 hours:
(1) A total
effective dose equivalent exceeding 5 rem (0.05 Sv); or
(2) A lens dose equivalent exceeding 15 rem
(0.15 Sv); or
(3) A shallow dose
equivalent to the skin or extremities exceeding 50 rem (0.5 Sv); or
b. 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 ALL This provision does not apply to locations where
personnel are not normally stationed during routine operations, such as
hot-cells or process enclosures.
c.
In addition to the requirements of paragraphs
"a" and
"b
" above, each licensee shall notify the Iowa department of public
health within 24 hours after the discovery of any of the following events
involving licensed material:
(1) An unplanned
contamination event that:
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 area;
2. Involves a
quantity of material greater than five times the lowest annual limit on intake
specified in Appendix B for the material; and
3. Has access to the area restricted for a
reason other than to allow isotopes 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:
1. The
equipment is required by regulation or license condition to prevent releases
exceeding regulatory limits, to prevent exposures to radiation and radioactive
materials exceeding regulatory limits, or to mitigate the consequences of an
accident;
2. The equipment is
required to be available and operable when it is disabled or fails to function;
and
3. 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
spreadable 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:
1. The
quantity of material involved is greater than five times the lowest annual
limit on intake specified in Appendix B for the material; and
2. The damage affects the integrity of the
licensed material or its container.
(3) The licensee or registrant shall prepare
each report filed with the agency pursuant to 40.96(136C) so that names of
individuals who have received exposure to sources of radiation are stated in a
separate and detachable portion of the report.
(4) Licensees or registrants shall make the
reports required by 40.96(1) and 40.96(2) to the agency by telephone, telegram,
mailgram, or facsimile.
a. Licensees or
registrants making initial reports to the Iowa department of public health
shall to the extent that the information is available at the time of
notification include:
(1) The caller's name
and call-back telephone number;
(2)
A description of the event, including date 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.
b. Each licensee or registrant who makes a
report required by 40.96(1) or 40.96(2) shall submit a written follow-up report
within 30 days of the initial report. Written reports prepared pursuant to
other rules may be submitted to fulfill this requirement if the reports contain
all of the necessary information. These written reports must be sent to the
Iowa Department of Public Health, Bureau of Radiological Health, Lucas State
Office Building, Des Moines, Iowa 50319. The reports must include the
following:
(1) A description 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 exposure of individuals to
radiation or to radioactive materials without identification of individuals by
name.
(5) The
provisions of
641-40.96
(136C) 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
641-40.98
(136C).
