TROXLER MOISTURE DENSITY GAUGE INADVERTENTLY BUMPED BY TRUCK
The following summary information was provided by the licensee via telephone:
On 7/31/2023 at about 0730 MDT, employees of the City of Great Falls were standardizing a Troxler moisture density gauge (contained 9 millicuries of cesium-137 and 44 millicuries of americium-241) with the gauge on an asphalt lot and the source in its cage; as per standard practice. A loader truck inadvertently hit the gauge but was halted before it ran over the gauge. Some plastic on the gauge was damaged. The licensee halted operations and restricted access. Subsequently, radiation levels of 0.294 millirem per hour at 1 foot and 0.004 millirem per hour at 4 feet were measured, which were essentially background levels. No overexposure or other personnel injury were reported.

AGREEMENT STATE REPORT - GAUGE SHUTTER STUCK SHUT
The following is a summary of the information provided by the Oregon Health Authority via email:
At 0830 PDT on August 1, 2023, during the 6-month shutter check and 3-year wipe test on the number 1 digestor level source, the licensee discovered a corroded shear pin that allowed the lever to detach from the source, leaving the source in the closed position. The current state of the source was verified closed with a survey meter. The licensee repaired the sheer pin and tested the mechanism. The source was working correctly and returned to service by 0922 PDT.

RADIOACTIVE SOURCE LOST IN TRANSIT
The following information was received from Elkhart Clinic via telephone:
A 300 micro-curie germanium-68 (Ge-68) phantom source was sent from Elkhart Clinic of Elkhart, Indiana, in Siemens Medical Solutions in Knoxville, Tennessee, via [common carrier] on November 22, 2022. The radioactive source never arrived at its destination and was subsequently declared lost by [common carrier]. Ge-68 is used as a quality control source for positron emission tomography (PET) studies.
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.
