Matt Falke notified Office of Emergency Services on Sunday 9-11-05 of the theft of his Soil Moisture Density Gauge from a secured container located in the bed of his truck parked in the driveway of his home. Matt Falke thought he had called RHB [Radiological Health Branch] but in fact was speaking with OES who transferred him [to] the DHS Duty Officer of the day. Bill Potter of OES sent RHB actual notification on Monday, Sept 12 of the event. Local police and Modesto and Sacramento FBI field offices have been notified. The device has been identified as a CPN 503DR Hydroprobe containing 50 mCi of AmBe241 [Americium-241-beryllium] with a serial number H33024767. Matt Falke is checking the local Flea Market today to see if the item will be offered for sale and is putting a reward offer in the local newspaper.
Less than the quantity of an
IAEA Category 3 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. For some of these sources, such as
moisture density gauges or thickness
gauges that are
IAEA 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.
