| Event Description | The following information was provided by Alabama Radiation Control (the Agency) via email:
Licensee reported that a Honeywell model 4202 beta gauge serial number AE1345 was found with shutter stuck in the safe/closed position during routine shutter checks. The gauge's source, an Eckert and Ziegler model PHC.C2, is promethium-147 with 210 millicuries of activity as of 1/9/2023. The maximum exposure rate at 12 inches from the gauge was reported to be 0.03 mR/hr, less exposure than at installation. The licensee reported that no personnel received radiation exposures over background, due to the shutter's position and that the area around the gauge is unoccupied. Reported to the Agency 1/10/23. Alabama Radiation Control will provide more information as the investigation continues. |
