The following is a summary of information received via email:
On August 24, 2020, the licensee notified the New Jersey Department of Environmental Protection of two lost sealed sources. The sources had been sent from the licensee's Austin, Texas facility to their Fair Lawn, New Jersey facility, and are reported as missing by the shipper. The two sources were Ni-63 foil sources with an activity of 10 mCi each (S/N: AO-2484 and AO-5478). Each source was in a Life Technology Holdings, model Trace 1300, electron capture detector (S/N: 719420216 and 719420261).
The shipper has been searching for the sources, but at this time considers them missing with little likelihood of recovery. The shipper's tracking system indicates that the sources were delivered to the licensee's Fair Lawn facility, but that location has stated they never received the sources. The address to which the sources were reportedly delivered does not exist and the person who reportedly signed for the package is unknown to the licensee.
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.
