1. Number in parentheses is percent error (two standard deviations) of total radioactivity content of sample.
2. Cesiu11-137 and Zinc-65 radioactivity were corrected back to the date of collection.
Gross beta radioactivity is given for the date of ounting (July-August 1970);
3. 0.0 (0%) signifies that the activity in the sample was less than the minimum
detectable limit. -
