The State of
California provided the following information via email:
On December 5, 2012, . . . American Soil Testing notified RHB [California Radiologic Health Branch] that his storage facility had been broken into and two CPN Moisture Density gauges (Serial numbers MD00405615 & M17031878) had been stolen. The licensee was advised to post a notice and reward in the local newspapers and on Craigslist and to notify local law enforcement.
Note: Miscommunication resulted in the NRC not being notified until 4/8/13.
CA 5010 Number: 120512
These CPN Moisture Density gauges contain two (2) sources each, i.e., 10 mCi Cs-137 and 50 mCi Am-241/Be.
HOO Note: See EN#48867 - Report from Nevada concerning recovery of M17031878 gauge.
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.
