The state submitted this report via fax:
On June 27, 2008 a representative of Georgia Pacific called to report the loss of an NRD static master ionizing unit Model 2u500 containing 500uCi of Po-210. A written report was received on July 7, 2008. These units have no serial number associated with them. They are used to control static on analytical balances. The balance with the missing static bar was put in a storage area for the lab. The probable disposition of the static bar is that it was either returned to the manufacturer or accidentally disposed of in the facility trash, which goes to the Winnebago County landfill. No exposure to individuals is probable. The general licensee conducted on extensive search of their facility, and instituted new procedures to prevent reoccurrence.
Wisconsin event: WI080007
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.
