NUCLEAR REGULATORY COMMISSION
OFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDS
WASHINGTON, D.C. 20555-0001
December 9, 2003
NRC INFORMATION NOTICE 2003-22:
HEIGHTENED AWARENESS FOR PATIENTS
CONTAINING DETECTABLE AMOUNTS OF
RADIATION FROM MEDICAL ADMINISTRATIONS
Addressees
All medical licensees and NRC Master Materials License medical use permittees.
Purpose
The U.S. Nuclear Regulatory Commission (NRC) is issuing this Information Notice (IN) to alert
addressees of an event where a radiation detector, installed as part of heightened homeland
security measures, alarmed when a recently released radiopharmaceutical patient passed by it.
In reviewing this notice, licensees are also reminded to emphasize to those patients still
containing detectable amounts of radiation from medical administrations and released with
written instructions in accordance with 10 CFR 35.75, the importance of following those
instructions. This is essential for maintaining doses to other individuals as low as is reasonable
achievable and, presently, to reduce the occurrence of patients triggering with radiation
monitors, installed at public locations for increasing public security in the United States.
It is expected that recipients will review this information for applicability to their licensed
operations and consider actions, as appropriate, to avoid similar problems. However, suggestions contained in this IN are not new NRC requirements; therefore, no specific action
nor written response is required.
Description of Circumstances
On March 20, 2003, a bus traveling from New York to Atlantic City set off a radiation alarm in a
tunnel, as it passed by a radiation detector. When the State Police pulled over the bus, it was
discovered that one of the passengers had received a 370 Megabecquerel (10 millicurie) dose
of iodine-131 earlier that day from a medical procedure. Although the medical licensee
provided the patient with written safety instructions, which included not using public
transportation for 2 days, the patient failed to follow the instructions. This resulted in the
activation of the radiation detector in the tunnel. Subsequent discussions with the patients
physician indicated that the patients actions in taking the trip would have no safety significance
to the members of the public on or near the bus. However, the event resulted in unnecessary
concern and inconvenience to the patient and members of the public, as well as to law
enforcement authorities and other public officials.
Discussion:
Heightened security measures are now in effect throughout the United States. These include, but are not limited to, installation of radiation surveillance equipment at critical infrastructures
and mass congregation events. Therefore, types of incidents such as the one described within
this IN are likely to increase for released patients that still contain detectable amounts of
radiation from medical administrations of radiopharmaceuticals and brachytherapy sources.
These incidents may not be limited to those patients who are required to be provided written
instructions, when released in accordance with 10 CFR 35.75, but could also include patients
administered diagnostic dosages or low-level therapeutic dosages of radiopharmaceuticals. In
the example above, if the patient had been administered less than 259 Megabecquerel
(7 millicurie) of iodine-131, NRC regulations would not have required that the licensee provide
the patient with written instructions, but the patient might still have set off a radiation detection
alarm.
When licensees are required to provide written directions to patients released in accordance
with 10 CFR 35.75, the licensees are expected to, among other things, review with authorized
users the expectation that written instructions provided to patients will be followed. Accordingly, authorized users are expected to evaluate the patients capability to follow recommended
written instructions before release, to determine if release at that time is advisable, and stress
the importance to the patient of following the written instructions.
In view of the event described and its potential for becoming more common, licensees should
consider the following voluntary actions for all patients who still contain detectable amounts of
radiation after receiving diagnostic or therapeutic quantities of radiopharmaceuticals or
brachytherapy implants:
1.
Released patients who are administered diagnostic or therapeutic quantities of
radiopharmaceuticals or brachytherapy implants should be aware that their
treatment may have additional implications, because of heightened security
measures. Accordingly, provide all patients that still contain delectable amounts
of radiation with an appropriate explanation about the potential of alarming
radiation monitoring equipment.
2.
To assist the patient and avoid unnecessary concern by law enforcement
authorities and other public officials, consider providing the patient with the
licensees business card and written information for law enforcement use, stating
that the radiation received by the patient poses no danger to the public and that
it is allowed by NRC medical use regulations. This IN requires no specific action nor written response. If you have any questions about the
information in this notice, please contact one of the technical contacts listed below or the
appropriate regional office.
