| Title | Agreement State Report - Low Level Alpha Radiation On A Shipping Container |
| Event Description | The following information was received via e-mail:
On 8/21/2015 at 1550 [MDT] an incident involving radioactive material was reported to the Utah Department of Environmental Quality's 24 hr. hotline. The caller reported low level alpha radiation activity on an empty shipping container and roll-off box that exceeds DOT standards. The container arrived at their facility the morning of 8/21/2015 from a Utah (NRC Agreement State) regulated facility near Blanding. It was the belief of the caller that it is very unlikely there was any dosage to humans or the environment. The container was shipped from Blanding, Utah to Douglas, Wyoming through Grand Junction. The caller has notified the NRC [National Response Center], Incident #1126333. They have also contacted Colorado and Wyoming DOT. Utah Event: UT15-0003
The source of the alpha radiation was natural uranium. The container was decontaminated. A radiation survey of the container was conducted before decontamination with the following results: Direct alpha readings of 2437, 7616, and 6092 dpm per 100 square cm Removable alpha readings of 191, 200, and 786 dpm per 100 square cm. These results are below the DOT 49CFR173.443(a) reporting requirements Notified the R4DO (Warnick) and NMSS Events Resource (via e-mail).
The following information was received from the State of Utah via email: After further investigation into this incident, the DWMRC [Division of Waste Management and Radiation Control] has concluded that the reported incident was in error and that DOT standards were not exceeded. The DOT alpha contamination limits found in 49 CFR 173.443(a) are for removable (non-fixed) contamination. The incident was reported on an incoming survey results for direct alpha measurements and not on removable alpha measurements. The removable alpha measurements from the same incoming survey were below the DOT alpha contamination limits. Therefore, the State of Utah is requesting to retract this incident (EN#51359)." Notified R4DO (Warnick) and NMSS Events Notification group via email. THIS MATERIAL EVENT CONTAINS A "NOT RECORDED" LEVEL OF RADIOACTIVE MATERIAL |
