EERF (Eastern Environmental Radiation Facility) standard operating procedures for radon-222 measurement using charcoal canisters

Technical Report ·
OSTI ID:6282254
The passive nature of activated charcoal allows both adsorption and desorption, and, in addition, the adsorbed radon undergoes radioactive decay during the exposure period. Therefore, the canister cannot uniformly integrate over the entire exposure period. However, the canisters can be calibrated to yield precise results for radon concentrations in structures during the deployment period of 48 hours used by the US Environmental Protection Agency (EPA).
