222)Rn has been increasingly used to identify groundwater contribution to surface water. Particular attention has been paid to analytical protocols and counting parameters used for liquid alpha scintillation measurements over a range of activities covering river and groundwater domains. Direct measurements and Rn-extraction protocols are optimized, and scintillometer efficiency is calibrated using international standards over the 0.5-35 Bq/L range. The interval of activities was performed in surface water and groundwater from a small Canadian watershed. Copyright © 2013. Published by Elsevier Ltd.
