Abstract
The pulse-height distributions from known amounts of 222Rn and its daughters were measured as a function of the volume of the scintillator solution and compared with the air luminescence spectrum from α-particles in air. The results indicate that 222Rn and its daughters in the gaseous space above the liquid scintillator produce the air luminescence counts which lead to errors in quantitative determination of 222Rn by liquid scintillation counting unless necessary corrections for the counts are made. The error inherent in the conventional determination of 222Rn by liquid scintillation counting is evaluated. Methods for correcting the air luminescence counts are discussed.
