J. Sabol et al., MONITORING OF RN-222 IN TAIWANESE HOT-SPRING SPA WATERS USING A MODIFIED ELECTRET ION-CHAMBER METHOD, Health physics, 68(1), 1995, pp. 100-104
Rn-222 concentrations in some Taiwanese hot spring spa waters have bee
n monitored using commercially available electret ion chambers (EIC).
The use of two EIC units for measuring radon concentrations in the air
phase and voltage dependent correction factors for subtracting gamma
contributions resulted in improved accuracy.
