Title	Agreement State Report - Unplanned Explosion Damaging Mixture of 400 Millicuries of Carbon 14
Event Description	This information was emailed from the state as follows: During a routine health and safety inspection, the [state] inspector learned that an explosion had occurred at the facility on December 3, 2009. An Authorized User was quenching a mixture containing 400 milliCuries of Carbon-14 at the time of the explosion. The individual showered and was taken to the emergency room. The individual had several bioassays done prior to returning to work. The licensee decontaminated the area of concern within the lab. Iowa Item Number: IA100005 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf 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
