Abstract

A study on the use of 3M Empore™ Radium RAD disk for the rapid and direct determination of 226Ra and 228Ra concentration in drinking water samples by means of liquid scintillation spectrometry is described. Three cocktails and several treatments were tested in order to improve the knowledge on the energy transfer between the alpha or beta—particle emissions of the isotopes fixed in the RAD disk and the cocktail. The sources of variability of this method were compared with the elution method, in which radium is stripped from de RAD disk and measured by liquid scintillation spectrometry using a Quantulus 1220™.
