| Title | Agreement State Report - Damaged Gauge |
| Event Description | The following information was obtained from the state of Washington via email:
Earth Solutions NW (ESNW) reported that a moisture/density gauge (CPN model MC-1-DR, serial #MD60308232) was crushed on 7/2/2013 at temporary jobsite in Mill Creek, Washington. The gauge contained a 1.85 GBq (50 mCi) Am-Be source (model CPN-131, serial #AM8232) and a 0.37 GBq (10 mCi) Cs-137 source (model CPN-131, serial #C8232). The gauge operator had placed the gauge in front of his truck. When asked to move his truck, he forgot about the gauge, moved the truck forward, and crushed the gauge. The source rod was retrieved using a shovel and placed in a bucket of sand. Radiation surveys revealed no radioactive contamination at the jobsite. The source rod and other parts of the gauge were returned to the ESNW facility. On 7/17/2013, Hevly Technical Services (gauge contractor) and Washington Department of Health personnel performed leak tests on the Cs-137 and Am-Be sources. Washington State Public Health Laboratories analyzed the leak test samples and detected no radioactivity. The Cs-137 source rod was reinserted into the gauge body and secured with duct tape. The gauge was then placed into its shipping container. Hevly Technical Services transported the gauge to Qal-Tek Associates (radioactive waste broker) for disposal. To prevent recurrence, ESNW provided additional training to gauge users on proper handling, transporting, storage, and emergency procedures. NMED Item Number: 130311 |
