The following information was provided by the
New Jersey Department of Environmental Protection (
NJDEP) via email:
On September 9, 2024, during a routine inspection of the licensee, information for the exit sign was provided to the radiation safety officer (RSO). The inspectors asked for the sign's location and for the facility contact listed to be updated if necessary. After the inspection, follow up emails and searches of the facility led to the determination that the sign could not be located. The sign's manufacturer was contacted to confirm whether or not the sign might have been returned. SRB Technologies (the manufacturer) confirmed that the sign was not assigned a return number, and that paperwork for its return was not submitted. After additional follow up with the RSO, and final search of the facility, it was determined that the sign has been lost.
New Jersey Event Report ID number: To be determined.
Additional information: The lost exit sign contained approximately 9210 millicuries of tritium (H-3).
THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as
moisture density gauges or thickness
gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
