| Title | Lost Radioactive Material Found in Scrap Yard |
| Event Description | Material received at scrap yard on August 5, 2008. Wisconsin DHS verified via phone that material was locked in a secure location from members of the public. On August 7, 2008 DHS investigated the radioactive material, a compacted 55 gallon drum with multiple pieces of scrap inside drum. A mini-spec GR-135DN was used to determine the source of radiation as Ra-226. Radiation exposure and contamination surveys were conducted on the outside of the compacted drum. The maximum exposure observed was 500 uRem/hr. The contamination survey on the drum found no contamination. DHS staff tried to locate the source of radiation inside the drum where the highest radiation levels were located. During the attempt, several pieces of scrap were removed and surveyed and no radiation above background except for one piece that read above background. Material was properly tagged and bagged. The staffs gloved hands were frisked and contamination was present. Individual doffed gloves and re-performed hand frisk and no contamination was found. The staff halted any further handling activities at this time to prevent any possible spread of contamination. The material was properly tagged, bagged and stored at the scrap yard in a locked holding area that is not accessible by members of the public. DHS is exploring options to properly dispose of this radioactive material.
State Event Report: WI080008 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. This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |
