内容記述タイプ Abstract
内容記述 For the collection of HTO and HT in the atmosphere, the air passing through a filter is introduced into a molecular sieve column to collect the HTO species and the resultant dried air was mixed with H_2 and O_2 carrier-gas generating from the electrolysis of extremely low tritium-bearing water. The mixed air was mutually reacted in the Pd-coated catalyst column to give water, followed to another molecular sieve column to adsorb the newly synthetic water for the evaluation of HT concentrations. The tritium concentration in each water fraction and in the collected precipitations was counted by the liquid scintillation method using Aquasol II scintillator. The results, summarized in Fig. 3 and Table 2, obviously show that the HT concentration is maintaining almost constant value of 1-2 pCi/m^3 -air during all seasons. On the other hand, the HTO concentration is remarkably influenced by the collecting months; having lowest tritium concentration in winter while the highest concentration (corresponding to about 3.0 pCi/m^3 -air) appears in July and followed by the gradually decreasing tendency from the end of summer. In the case of precipitations, the average tritium concentration was evaluated to be 76 pCi/l for all precipitations collected from July 1983 to June1984 in Niigata area. These fundamental data will serve for the hydrologic applications of tritium like the estimation of exchange period of groundwaters, as well as the assessment of background tritium level before the operation of nuclear electric power stations.
