AGREEMENT STATE REPORT - LOST STATIC ELIMINATOR
The following is a synopsis of information provided by the Colorado Department of Public Health and Environment via email:
The licensee reported the loss of one static eliminator (NRD model P-2021) containing 10 mCi of Po-210. This is being reported in accordance with Colorado Regulations Section 4.51.1.1 (10 CFR 20.2202(a)(1)).
Colorado Event Number: CO230020
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 REPORT - DAMAGED GAUGE HANDLE
The following information was provided by the South Carolina Department of Health and Environment (the Department) via email:
"On July 20, 2023, at 1507 EDT, the Department was notified by the licensee that while performing semi-annual shutter checks the licensee discovered that the handle on a Berthold LB7440D had broken off which prevented the shutter from being locked. The licensee cordoned off the area and was able to rotate the shutter to the closed and shielded position. The gauge is a Berthold Model LB7440D s/n FT314 and contains a 30 mCi Cesium-137 source. On July 21, 2023, BRH [Bureau of Radiological Health] on-call duty officer met licensee's RSO at 0800, to perform a visual inspection and radiation survey of the gauge. The highest radiation measured was 0.2 mR/hr. The licensee has contacted a licensed vendor to schedule the repair of the handle. "

DOSE TO AN EMBRYO
The following information is a summary of a phone call with the North Kansas City Hospital Radiation Safety Officer (RSO):
On May 10, 2023, a nuclear medicine tech administered 125.7 mCi of I-131 to a patient for the thyroid cancer ablation at North Kansas City Hospital. The patient had received a pregnancy test on May 8, 2023, which was negative.
On July 21, 2023, the hospital was notified that the patient was pregnant with an estimated fetal age of 7-10 weeks which would have had the patient pregnant at the time of administration, or shortly thereafter. This event is being reported because of the potential for a dose to the embryo.
At this time there are no known negative effects to the patient.
