Specifically, the data will be processed to provide total gamma vay exposure rate isotope (e.g. (extrapolated to the 1 meter level) 24 A, 137 oe. and 60 Co) . and selected concentration contours. a Minimum tye c . 241 : detectability on the order of 5 pCi/g for Am and less than 1 pCi/g . for 137 6 ~~’Cs and OG can be obtained with this system.
