222Rn 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.
► Several analytical tests were developed to optimize protocols for 222Rn measurements in water. ► Two analytical procedures, direct and extraction methods were found in order to guarantee a 0.5–35 Bq/L range of measurement. ► A specific test has been conducted to evidence that both methods are well calibrated. ► Those protocols have been tested on water from a small Canadian watershed.
