Abstract
An instrument and methodology are described for the measurement of Po- 218+ ions immersed in carrier gases in hydrostatic equilibrium. This e lectrostatic precipitation device has a 7.5-1 volume and an absolute d etection efficiency of 10.2%. An improved analytical method is develop ed to determine neutralization rates over wide ranges of both Rn-222 c oncentrations (100 to 50 000 Bq/m3) and neutralization rates (0.05 to 1 s-1). Applications to the radon-in-argon and radon-in-air cases are presented, and appropriate intercomparisons involving previous results are discussed.
