ABSOLUTE MEASUREMENTS WITH A 4 $pi$-COUNTER
Technical Report
·
OSTI ID:4257957
Measurements on standardized 6 wt.% Ru-U all emitters were made in a 4- The effects of proportional flow counter. The counter efficiency was found to be near 100%. Absorption curves were determined with plastic foils and aluminium. A comparison is made between the self-absorption arising in different methods of source preparation which include precipitates and the use of wetting agents. The most reliable results were obtained with sources on aluminium foils where the foil absorption was calculated from the absorption curves and the seif-absorption is supposed to be negligible for isotopes with end point energy above 0.5 Mev. The 6 wt.% Ru-U all -emitters studied have energies ranging from 1.71 Mev (P/sup 32/ to 0.167 Mev (S/sup 35/. (auth)
