A scrap yard operator contacted the
Indiana State Department of Health to request investigative assistance after their radiation monitor alarm sounded while monitoring a batch of trash. A Health Physicist was dispatched to the scrap yard and discovered a
Cesium-137 source in the trash. Upon further investigation it was determined that the source belonged to a general licensed company which was no longer in operation. The company owned two like sources, but only source CS4464 (S/N 4699931) containing 14 millicuries of
Cesium-137 was found. The found source is not leaking and it has not caused any injury to personnel. The
Indiana State Department of Health has contacted Region III and will continue looking for the other missing source.
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.
