WASHINGTON, D.C. 20555 March 1, 2007 NRC REGULATORY ISSUE SUMMARY 2007-03 IONIZING RADIATION WARNING SYMBOL
ADDRESSEES
All U.S. Nuclear Regulatory Commission (NRC) licensees and certificate holders. All Radiation Control Program Directors and State Liaison Officers.
INTENT
The NRC is issuing this regulatory issue summary (RIS) to inform addressees that on February 15, 2007, the International Organization for Standardization (ISO) released ISO
Standard #21482, Ionizing Radiation Warning - Supplementary Symbol , which describes a new supplemental symbol to warn individuals not trained in radiation safety of the presence of a
large source of ionizing radiation. The ISO supplemental symbol does not replace the standard
radiation symbol (trefoil). The information in ISO Standard #21482 and this RIS are not new
NRC requirements; therefore, no specific action or written response is required.
BACKGROUND
At the December 2000, International Conference of National Regulatory Authorities withCompetence in the Safety of Radiation Sources and the Security of Radioactive Materials
, participants discussed concerns about the increasing number of radiation events involving the
International Atomic Energy Agency (IAEA) Category 1 and 2 sources (later expanded to
Category 3 sources) that caused death or serious injury. Conference attendees concluded that
the trefoil had no inherent meaning to individuals, such as children, who had not been trained in
radiation safety. As a result, the conference recommended that a universal system of labeling
large radioactive sources be developed, as a supplement to the trefoil, that would target any
citizen, anywhere in the world with the message: "This object is dangerous and should be left
alone," as well as to convey without words that one needs to "Run Away".
On September 10, 2001, the IAEA General Conf erence approved the development by ISO of a new standard specifying the supplementary warning symbol. In 2005, IAEA designed a number
of symbols with different colors and shapes and evaluated them in a series of assessments and comparisons with over 1600 people having insufficient technical education or background, children, and different cultures in 11 different countries (including the United States) to narrow
down the choice.
In July 2006, the ISO Secretary reported that 14 countries (including the United States)
approved the standard, three countries approved with comments, two countries abstained, and
two countries disapproved. NRC did not represent the United States on this matter but has
followed the development of the supplemental symbol. NRC has not initiated rulemaking, nor
does it intend to at this time, to address this matter and there are no new requirements for
licensees.
SUMMARY OF ISSUE
The new supplemental symbol is shown in Enclosure 1. As discussed in ISO Standard #21482, IAEA recommends that the supplemental symbol be used for IAEA Category 1, 2, and 3 sealed
sources. The activity for Category 1, 2, and 3 sources are in Enclosure 2. This symbol would
supplement the trefoil, not replace it. As suggested, the supplemental symbol should be placed in close proximity to the source preferably on the shield or near the point of potential access to
the source. The intent of the symbol on the sh ield is to convey the message that dismantling the device is very dangerous.
Due to the small size of most sources, placing the symbol directly on the source might not be practicable. Placing the symbol on the device shielding so it can be seen prior to accessing the
actual source is desirable. The supplemental symbol shall be closely associated with the
device housing the source, as a warning not to dismantle the device or get any closer to the
source. ISO Standard #21482 recommends, when practical, that the supplemental symbol be located directly on the source shield and under the device covers, such that it is not visible during
normal use but would be visible if anyone attempts to dismantle the device. If there is no device
cover, the Standard suggests that the symbol should be located on the outside housing in a
discrete location, clearly visible prior to disassembly, but not visible during normal use. The
supplemental symbol should not be used on a door to a room or in public areas, or on trucks or
shipping containers.
IAEA also intends to inform scrap yards, smelting operations, or places where radioactive material is not intended to be located aware of the supplementary symbol's use. IAEA also
plans to hold a workshop later this year to work on implementation strategies for how best to
retrofit the symbol on existing applicable sources. Some licensees that export sources to
countries that require this supplemental sy mbol may need to use the supplemental symbol, even though NRC does not require licensees to do so.
ISO published and released this standard on February 15, 2007. IAEA and ISO both made media announcements about the publication of the new standard. IAEA has gained agreement
from most source manufacturers to start using the symbol on new IAEA Category 1, 2, and 3
sources as soon as possible. There is no requirement for NRC licensees to adopt ISO
Standard #21482.
BACKFIT DISCUSSION
This RIS requires no action or written response. Any action on the part of addressees in accordance with the guidance contained in this RIS is strictly voluntary and, therefore, is not a
backfit under any regulatory requirement in 10 CFR. Consequently, the staff did not perform a
backfit analysis. FEDERAL REGISTER
NOTIFICATION

requirements.
