The following report was received from the State of
Minnesota by email:
The licensee uses a static eliminator on the end of an air line. Typically the static eliminator is kept on the line and not removed. The licensee recently moved locations and not all of their stations were set up, so they were moving the static eliminator around. The static eliminator was removed from a line and placed on top of a box. It slid off the box and ended up under a nearby pallet. They noticed the static eliminator was missing on 12/24/2018. The pallet was moved and the static eliminator was found on 1/11/2019. All of the stations are now set up and the static eliminator will stay connected to a dedicated line.
Material: Po-210, NRD model P-2021, 1.9 mCi on 1/10/19

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.
