Description
Concentration of tritium in the atmosphere was measured in Ibaraki, Japan. At first, sampled air was passed through a column of molecular sieve, and all the water vapour was removed. Hydrogen gas obtained by the electrolysis of water was added to the air, and oxidized by a Pd catalyst column, then the oxidized hydrogen was absorbed by a last column of molecular sieves. These columns of molecular sieves were dehydrated by heating at 400 deg C. The concentration range of atmospheric HTO and HT was 1-2 pCi/m3 in Ibaraki for a year. The concentration of atmospheric HTO varied depending on the content of water vapour in air. (J.P.N.)
