Event Notification Report for June 13, 2023

AGREEMENT STATE REPORT - STOLEN/FOUND SOURCE

The following information was provided by the Pennsylvania Department of Radiation Protection (DEP) via email:

"On June 1, 2023, an employee of the licensee reported to police that their vehicle, with a nuclear density gauge in it, was stolen earlier that day. The vehicle was located and returned to the employee within a few hours. The gauge was still properly stored in the trunk and untouched with no evidence that the trunk lock, gauge chain, chain lock, or gauge case had been tampered with. The DEP has been in contact with the licensee and will update this event as soon as more information is provided.
"Troxler Model Number: 3430
"Serial Number: 29846
"Cesium 137, 9 millicuries; Americium 241:Be, 44 millicuries"

Event Report ID No: 230017

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.

AGREEMENT STATE - STOLEN MOISTURE DENSITY GAUGE

The following was received by email from the Florida Department of Health, Bureau of Radiation Control (BRC):

"BRC received a call at 1045 EDT from the radiation safety officer of ECS Florida LLC. The caller stated that an Instrotek 3500 (#4012, AmBe K893/19, Cs137 BG1008) moisture density gauge was stolen from the back of a pickup truck on its way to a job site. The vehicle made several stops on the way and they do not know at which location it was stolen."

AGREEMENT STATE - FOUND DENSITY GAUGE

The following was received by email from the Texas Department of State Health Services [the Agency]:

"On June 1, 2023, a steel mill notified the Agency that a load of scrap coming into their facility set off the radiation alarm. The source was identified as an inline-type density gauge and it was secured at their facility until more information could be identified on the device to determine the owner. On June 5, 2023, the facility found a phone number on the gauge that stated to call Schlumberger if the gauge was found. Schlumberger was contacted and stated the gauge had been sold to Liberty Oilfield Services INC. The Agency and steel mill contacted the licensee which picked up the gauge the same day. The gauge was a Thermo-Fisher model 5192, Serial # B7615 containing 200 mCi (7.4 GBq) of Cesium-137. An investigation is ongoing into how the licensee lost possession of the gauge."
