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.

EN Revision Text: AGREEMENT STATE REPORT - FOUND MOISTURE DENSITY GUAGE

The following is a synopsis of an email received from the State of Florida:

The State of Florida received a call today around 1530 EST from a business to report they found a Humboldt Soil Moisture Density Gauge [Model 5001P, Serial number 547, 1988] in the gravel parking lot of their place of business. There was only a gauge without it's case. The gauge was found in an upright position, with the source rod appearing to be in the retracted position. The gauge did not appear to damaged, but does look to be very used and worn. The Tampa Bureau of Radiation Control Inspector was notified and is in route to investigate, secure the gauge, and transport it to the Tampa storage unit until it can be transported to the ERCE office in Orlando. The Tampa Police Department was also notified.

Humboldt literature from the internet shows the sources to be Cesium-137 less than 11 millicuries and Americium-241/Be less than 44 millicuries.
