ABSTRACT
A simple method for measuring (226)Ra in drinking waters has been validated and validation parameters are provided. It is based on the measurement by LSC of (222)Rn, at equilibrium with (226)Ra, which is absorbed into a water immiscible scintillation cocktail (Ultima Gold F) inside the counting vial. The validated application field ranges between the detection limit (2·10(-3) Bq/kg) to 150 Bq/kg. The method has proven to be reliable, effective and suitable for wide-range measuring campaigns. A summary of results obtained in recent years is also given.
