Event Description | EN Revision Imported Date : 9/3/2020
AGREEMENT STATE REPORT - ABANDONED RADIOACTIVE SCRAP METAL The following information was received via email: On 7/1/2020, Massachusetts Radiation Control Program was informed by Schnitzer Steel Industries, Inc., that a scrap metal shipment from Town of Littleton Transfer Station in Littleton, MA set off the radiation monitor alarm. The vehicle was redirected back to Littleton Transfer Station for follow-up survey and mitigation in accordance with MA RCP DOT Special Permit 10656 MA-MA-20-01. On 7/6/20, the material was identified and segregated from the scrap metal load by an independent radiation consultant. The radioactive material discovered was radium-226 Aircraft gauge. Device is intact and not leaking as a wipe test was done by radiation consultant. A Ludlum Model 9DP-1 ion chamber was used for direct measurements on the instrument. The dose rate at 6 inches from the instrument was 1 mR/hr. Dose rate outside of drum is less than 300 microR/hr. The radium-226 activity was estimated to be approximately 31.6 microCuries based on the dose rate measured. The RAM material is being stored in safe secure storage away from people and labeled as radioactive material held for proper disposal. This activity meets the 30-day event report requirement for lost or abandoned radioactive material greater than 10 times the quantities specified in 10 CFR 20 Appendix C, or the Massachusetts equivalent, 105 CMR 120.297 Appendix C, which is ten times reportable quantity for radium-226 (1 microCurie). The Massachusetts Radiation Control Program considers this event to be open until proper disposal of this instrument is confirmed. Event Docket No.: MA 19-4216 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.

The following information was received via E-mail and is the Agency's (Massachusetts Radiations Control Program) final update to this report: 1). Event Cause: Device abandoned or discarded by person(s) unknown. 2). Corrective Action: Device transferred for proper disposal at licensed facility. 3). Manufacturer of Source or Device: Not Available / Not Indicated. Device found in scrap metal load. 4). No additional information expected by Agency. 5). Agency considers this event to be closed. Notified R1DO (Ambrosini), NMSS Events Notification E-mail group and ILTAB E-mail group. |
