Surveyed contents of storage flask located at TNF. The lid was lifted off roughly 12" up and a pole monitor was swept over the opening. The fields of the combined items in the flask were 9.84 mSv/h at 12-24". Extrapolated, the field is approximately 3.7 mSv/h at 1/2 m.
The flask contains an indium blank off plate, ISAC beam window and some miscellaneous used water fittings. The ISAC window is probably the largest contributor to the field.
A list of the contents and the dates the were placed into the flask are attached to the top of the flask lid. |
