Lumagel Plus scintillator was selected as the most suitable scintillator for simultaneous collection of H-3 and C-14 by using mono-ethanolamin (MEA) solution.The influence of air temperature and humidity on the collection efficien cy of H-3 and C-14 was examined.As the result, when the weight of water in MEA was less than 1000mg, the samples became colorless without separation into two phases, and the collection efficiency of 99% and more was obtained for C-14 within the collection time of 3.7 hours.On the other hand, the collection efficiency for H-3 decreased with increase of the weight of water in the collected air, but it was more than 90% even at high temperature of 30°C and high relative humidity of 90%.It was found that this method is practically useful for simultaneous determination of H-3 and C-14 concentration in air.
