A maintenance technician at the 3M facility in Knoxville, Iowa discovered that a Thermo Fisher Scientific model SULP-77A fixed gauging device containing 661 milliCuries of krypton-85 had a shutter that was stuck open and would not close. This discovery occurred when the production line was shutdown for routine maintenance. The RSO [Radiation Safety Officer] and backup RSO were notified and the gauge was isolated with caution tape to prevent personnel from getting close to the device. 3M maintenance personnel are authorized to perform shutter repair under the supervision of the RSO or backup RSO by Iowa radioactive materials license number 0042-1-63-FG. The licensee will provide a written follow-up report once repairs have been completed and the cause of the failure identified. | A maintenance technician at the 3M facility in Knoxville, Iowa discovered that a Thermo Fisher Scientific model SULP-77A fixed gauging device containing 661 milliCuries of krypton-85 had a shutter that was stuck open and would not close.
