G. After counting, the petri dishes should be separated into two piles, above and below 20 net counts 241 Am. H. The weight of each sample reading above 20 net counts 241Am should be determined IL. Save for lab processing the following: J. and recorded. 1. Cans from which the sereening sample reads 20 counts 241 Am and above. 2. Petri dishes which read 20 counts 241 Am and above. 3. One tenth of soil samples (cans and petri dishes) reading less than 20 counts 4l am, Discard (in contaminated area) remainder of soil samples reading less than 20 counts 241Am, Reuse of cans and petri dishes of this category is optional.
