AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE

The Ohio Department of Health reported the following via email:

"On September 29, 2020, at 0948 EDT, the licensee reported the theft of a moisture-density gauge from their location, Cincinnati, Ohio. Due to heavy rain the evening of September 28, a technician left the gauge locked in a company truck outside the secure facility instead of moving the gauge inside the secure facility as required. At approximately 0730 on September 29, the locked box containing the gauge was discovered broken into and the gauge and storage container missing.

"The gauge is a Troxler model 3411-B with a 8 mCi Cs-137 and a 40 mCi Am-241/Be sources.

"A report was filed with the Cincinnati police."

Ohio Item Number: OH200009

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 - VEHICLE RAN OVER PORTABLE MOISTURE GAUGE

This is a summary of a call from the state of Mississippi Division of Radiological Health via phone:

A portable moisture density gauge, containing 9 mCi Cs-137 and 44 mCi Am-241/Be sealed sources, was run over by a vehicle at a construction site in Clinton, MS. No visible damage of the gauge was identified. The licensee's survey results were normal for a retracted source. The gauge was returned to a local office and the state will also perform a survey once they are on site. There was no exposure to personnel.

* * * UPDATE ON 10/01/2020 AT 1957 EDT FROM ART ROBERT SIMS TO BRIAN P. SMITH * * *

The updated report was sent from the state of Mississippi Division of Radiological Health via email:

"Off Norrell Road, off MS. 1-20 Clinton Mississippi Continental Tire Construction site off-ramp, the gauge user was on a noisy construction site with heavy equipment and ear protection requirements. The gauge user was taking a measurement and the high elevated Rubber Tire Roller used to pack asphalt did not see the gauge user. The gauge user yelled at him trying to get him to stop, but due to the noise and the driver not seeing him, the rubber tire roller ran over edge of Humboldt Moisture Density Gauge model 5001 Ser. No. 9624, only damaging the outer housing. The RSO was contacted, used a survey meter Troxalert Model 01754 calibrated 01/10/2020, and received readings of 6 mR/hr which are consistent with previous readings that indicate the source was in the shielded position. The gauge is at the RSO's office and is being sent to Humboldt for electronics and housing repair and a wipe test. The incident was an accident. No violations could be issued to the licensee due to gauge user being present taking moisture readings and the driver of the rubber tire packer just did not see him."
