A comparison between the canister method and the ROAC system for radon emanation rate measurements

Creators

Description

Two methods for measuring radon emanation rates which rely on the adsorption of radon onto activated charcoal and subsequent gamma counting were compared. The ROACs were found to measure 38% of the values obtained by the charcoal canisters. This was probably due to radon loss arising from poor seals at the ground-air interface. The difference in sampling efficiency was determined to be about 10-15%
