EN Revision Text: AGREEMENT STATE REPORT - LOST I-125 SEED

The following information was received by the State of Ohio via email:

"The licensee performs prostate seed implants on Tuesdays and Thursdays each week. End of day inventories are performed by two therapists. At the end of day inventory on 1/4/2022 the licensee had 53 unused seeds. The beginning of day inventory on 1/6/2022 the inventory was 52 seeds. No procedures were conducted between 1/4/22 and 1/6/22, and surveys did not locate the missing seed. The licensee is unable to account for the discrepancy in their inventory."

Source/Radioactive Material: SEALED SOURCE BRACHYTHERAPY
Manufacturer: BARD Brachytherapy
Model Number: STM-1251
Radionuclide: I-125, 0.000393 Ci

Ohio Item Number: OH220001

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.

The following was received from the State of Texas (the Agency) via email:

"On January 10, 2022, the licensee notified the Agency that on Saturday, January 8, 2022, one of its technicians had taken a Troxler 3440 moisture/density gauge (SN: 37429) to their residence after completing a job and left it secured in the back of his pick-up truck. On the morning of January 9, 2022, the technician discovered the gauge had been stolen from the truck and reported the theft to his supervisor and a report was made to the police. The licensee has notified the local gauge service company, will search the area where the gauge was stolen, and will investigate posting reward poster(s). More information will be provided as it is obtained in accordance with SA-300."

Activity of the sealed sources are not known at this time. Troxler specifications indicate the typical sources to be Cesium-137 (8 mCi) and Americium-241/Be (40mCi) at the time of manufacturing.
