LIVERMORE: LAWRENCE RADIATION LABORATORY TO; Don Rawson FROM: Floyd Momyer Attached are. results obtained for tritiated -water in dust samples taken from various locations in the Sedan crater* Notes heading the table explain our procedure. 2) All tritium counts are as of l/l5/64* ;s- '' 4) "Loose" water off at 100°C^ 3**^: hours till distillation rate 5) "Bound" water off at 500°C; 3-4 hours till distillation rate 0) Ran two soil samples for Pot 1* Quoted errors are standard deviations of individual measurements from the mean. These errors should be an estimate of reliability for all the data. Statistical errors in counts were negligible in all cases. UNIVERSITY OF CALIFORNIA — (Letterhead for Interdepartmental use)
