The following was received from the
Illinois Emergency Management Agency via e-mail:
A graduate student affiliated with the University of Illinois reported the loss of two generally licensed NRD Model P-2042 static eliminators (5 mCi/Po-210, Serial Numbers A2KX694 and A2KX695). They were shipped on March 3, 2017, whereupon he proceeded to perform small neutron experiments. The devices were then put into a storage building and subsequently lost during a move to a new location sometime in November 2017. He believes the devices went to a landfill. At the time of loss they would have decayed to around 1.5 mCi each. By today's date, they would have decayed to approximately 200 uCi each.
In August of 2018, the general licensee reported it to NRD, Inc., and they referred him to the Illinois Emergency Management Agency. A report was received on the matter on November 19, 2018. The investigation is ongoing.
State of Illinois Item Number IL180043
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.
