| Title | Agreement State Report - Contaminated Area |
| Event Description | The agreement state provided the following information via facsimile:
During response to a fire, an on-site response personnel monitored area dose rates of 4 mrem/hour beta dose at waist level in an area about 20 meters east of building. On 06/29/07 Agency representatives and licensee confirmed area dose rates. Area was on pavement inside a fenced area. Caution tape was used to isolate the area. The licensee does not have regularly scheduled work hour on Friday, so the contract RSO said he will respond on Monday. This event does not appear to be related to the fire on-site [EN# 43447] because there is visible metallic contamination in the proximity of scrape-like tracks in the pavement. Suspected contaminate is DU. Discovery date and time was 06/27/07 at 02:00 EDT.
The following information was provided as an update: On 7/2/07 contract RSO performed survey of the area. Licensee sealed the most active area with roof coating (thin non-fibrous roofing cement). Dose rates were reported to drop by a factor of 2. When the coat cures the licensee will add another coat. Rough calculation confirmed this spill is greater than 5 X 105 CMR 296 B values. Because Starmet was required to provide multiple agency access to this area as part of CERCLA cleanup, it is unlikely that the cause of the event or the responsible party will be identified. Notified R1DO (Rogge) and FSME (Moore). |
