In the method, by measuring Cherenkov light generated when airborne radon and thoron are adsorbed to an absorbent and then β rays emitted in process of disintegrations of radon and thoron pass through the absorbent, radon and thoron are measured. Based on a decay time of the Cherenkov light, a mixture ratio between radon and thoron is measured. As the absorbent, porous glass is preferably employed which is provided with fine pores of 0.3 to 30 nm in diameter. | 08-13-2009 |
