| event text = The following information was received from the State of Arizona via email:
At approximately 10:00 AM on March 28, 2012, the Agency [Arizona Radiation Regulatory Agency (ARRA)] was informed that radioactive material had been detected by the Tempe, AZ Fire Department in an old flour mill.  The Agency [ARRA] dispatched a response team to the site to locate and confirm information.  The response team determined that the isotope involved is Cesium-137 and based on the label information approximately 25 millicuries remain in the device.  The device is labeled on the accessible surfaces as a Kay Ray Model 7107 gauge and also as a Model 7519B gauge assembly SN 13454.  Based on the site history and the labels, it appears that the device was transferred to Bay State Milling in the 4th quarter of 1980 or the 1st quarter of 1981.  The Agency [ARRA] did not issue a specific license for this site.  We assume that the device was transferred as a GL (Generally Licensed) device and remained in use into 1998.  Only about 10% of the site has been surveyed thus far.  The site security is being maintained by the Tempe FD (Fire Department).
