Title | Agreement State Report - Recovery of Two Moisture Density Gauges by an Arizona Licensee |
Event Description | The following information was provided by the State of Arizona via email:
Date: May 19, 2014 First Notice: 14-012 Arizona Licensee: N/A License No.: N/A On May 15, 2014, the [Arizona Radiation Regulatory] Agency was contacted by a licensee who stated that he was called about the disposal of a nuclear density gauge. The caller stated that they were not licensed and did not want to go to the regulatory agency but needed to get rid of the gauge. The caller also stated that if [the licensee] did not take the gauge, he would take it to a dumpster or leave it out in the desert. [The licensee] contacted the Agency on the afternoon of the 15th to discuss the situation. [The licensee] was contacted on the 16th and subsequently met the unknown caller and picked up the gauge. The gauge was brought to the Agency, where it was leak tested and secured. The depth moisture gauge came in two different wood boxes. The first box contained a Troxler depth moisture probe, model number 1255, with a 100 millicurie Americium-241:Be source and an origin date of 05/03/1975. The second box contained a Troxler depth density gauge, model number 1351, with a 7.7 millicurie Cesium-137 source and an origin date of 07/13/1982 The Agency continues to investigate the event. The State of Arizona will notify the Governor's Office and the FBI.
The State of Arizona identified the Arizona licensee who picked up and dropped off the sources at the Agency. The Am-241:Be probe/gauge has 3 labels on it with all different model and serial numbers. They are as follows: Model: 104a Serial #: J-3475 Model: 1255 Serial #: 810 Serial #: Am-239 Date: 5/30/75 The Cs-137 gauge has the same thing. They are as follows: Model: 504 Serial #: 212 Model: 1351 Serial #: 212 Model: 40-6475 Date: 7/13/82 [The Agency] crossed referenced the model/serial numbers in the NMED database and did not get any hits. Notified R4DO (Gepford) and FSME (via email). 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.
