GEIGER COUNTING OF TRITIUM AS WATER VAPOR. Final Report
Technical Report
·
OSTI ID:4818437
Results of an investigation on the se of water vapor plus Q-gas (98.7% hellum-1.3% butane) s a Geiger counting mixture are presented. If the counting system is heated to 100 deg C, water will exist as a gas or vapor at any partial pressure up to a maximum of 76O mm Hg. Q-gas may be introduced to the desired pressure. Both batch counting and flow counting methods were used. Useful plateaus exist at water vapor pressures up to 400 mm Hg with Q-gas added to glve a total pressure of 760 mm Hg. The counting efflclency decreases wlth increased water vapor pressure and is about 70% for water vapor pressures around 400 mm Hg. The operating voltage increases with increased water vapor pressure. Backgrounds are normal. Memory is less than 0.5% for the succeedlng sample and can be reduced to 0.02% by flushing several times with water. (P.C.H.)
