Incorporating Tritiated Water into a $$^{14}$$C-Sampling System for Quantitative Estimation of$$^{14}$$C Activity in Airborne Effluent

Koarashi, Jun   ; Akiyama, Kiyomitsu; Asano, Tomohiro; Yokota, Tomokazu*

Effect of incorporating tritiated water into a $$^{14}$$C sampling system on sample preparation and $$^{14}$$C activity measurement by liquid scintillation counting were investigated. Experiments derived the limit of water content in prepared sample, and also demonstrated that $$^{14}$$C activity can be determined without any interference from$$^{3}$$H contamination for clear-solution sample. The results enabled us to estimate permissible reelative humidity of air required for accomplishing sample preparation and $$^{14}$$C activity measurement. These showed that for sampling of air with less than the permissible relative humidity, total $$^{14}$$C activity in airborne effluent can be evaluated accurately with no dehumidification of air.
