| ENS 56716 | 5 September 2023 19:51:00 | The following is a summary from a report received via email from the Washington State Department of Health: A Troxler 3440 portable gauge (two sealed sources containing 9 mCi of Cs-137 and 44mCi of Am/Be-241) was run over by a bulldozer at a construction site. The full report with corrective actions has yet to be issued. No significant releases of radioactivity occurred. Washington Incident Number: WA-23-015 |
| ENS 56589 | 23 June 2023 19:53:00 | The following is a summary of the information provided by the Washington State Office of Radiation Protection via email: On 6/22/23 at 1419 PDT, the licensee identified that a 56.4 Ci Ir-192 radiography source could not be retracted into the exposure device (QSA Model 880D) due to a crank malfunction. The radiographer immediately contacted the Radiation Safety Officer who provided source recovery/retrieval actions along with crank mechanism fixes. The radiographer secured the source in the exposure device at 1422 PDT. The problem with the retrieval was identified as a loose securing nut that caused the crank to spin freely and the drive cable to come out of the crank conduit. During the incident, the radiographer's survey meter read 20 mr/hr at the crank location. A radiographer assistant expanded the boundaries and ensured the general public was not affected. The radiographer's total direct dosimeter reading after 6 normal radiography exposures and the source recovery actions were complete was 3 mRem. The incident took place at a temporary job site in Anacortes, WA. There were no overexposures or spread of contamination. WA Incident Number: WA-23-010 |
| ENS 56438 | 29 March 2023 17:00:00 | The following report was received from the Washington State Department of Health (WA State) via email: WA State received a licensee report of a stuck radiography source incident at 1606 (PDT) on March 28, 2023. The incident took place at the licensee's facility in Tacoma. The source guide tube was crimped, preventing the source drive cable from retracting into the device's shielded enclosure. A two milli-Roentgen per hour, radiation boundary was established, and the facility operations location/entrance was secured. No overexposures or spread of contamination occurred due to the event. Source retrieval/recovery actions have been completed. WA State was notified that the source was fully retracted into the shielded exposure device today, March 29, 2023, at 0430 (PDT). WA Incident No.: WA-23-006 |
| ENS 55860 | 26 April 2022 18:35:00 | The following is a summary of an e-mail received from the Washington Office of Radiation Protection: At 1323 PDT, Washington State received a report of two leaking electron capture detectors (ECD). The detectors failed leak testing and were removed from service. The licensee is working with the vendor on additional corrective actions. There was no spread of contamination and no overexposure. The ECD contain Ni-63 sources (model number G2397A and G1223A / serial number U37921 and F5004) with an activity levels of 0.0144 microCuries and 0.009 microCuries. Incident Number: WA-22-011 |
| ENS 55849 | 19 April 2022 19:45:00 | The following was received from the Washington Office of Radiation Protection via email: Incident took place on 4/15/22 at approximately 0800 PDT Wallula, WA. A fixed gauge (KayRay model 7062 bp; 50mCi Cs-137) was found unmounted and uncontrolled, nearby it's normally installed location. Source is intact and shutter mechanism has remained in the locked/closed position. No over exposure or spread of contamination. The fixed gauge is currently reinstalled at it's normal location, pending further investigation and report. Incident Number: WA-22-010 |
