Dear Mr. Shum:
Per your request we have calculated the average alpha and beta *6amma contamination levels in each of the buildin6s at the UNC site, Wood River Junction, RI.
The results are summarized in the attached table.
Averages j
presented represent the combination of individual averages for the floor.
wall, and ceiling surfaces, we1 hted by the total surface areas of these 6
individual surfaces.
Please note that ceiling activity levels were not i
included in the calculations for the Main Process and Pickle Liquor rooms of the Main Butiding, because those surfaces were surveyed by representatives of Region I, rather.than ORAU.
If you have questions, please contact me at FTS 626 3305.
Sincerely.
