Standard Test Method for Radium-226 in Water 

Importancia y uso:

5.1 The most prevalent of the five radium isotopes in ground water, having a half life greater than one day, are ²²⁶Ra and ²²⁸Ra. These two isotopes also present the greatest health risk compared to the other naturally occurring nuclides of equal concentrations if ingested via the water pathway.

5.2 Although primarily utilized on a water medium, this technique may be applicable for the measurement of the ²²⁶Ra content of any medium once the medium has been completely decomposed and put into an aqueous solution.

5.3 This test method is based on a method previously published by Rushing, et al. (1).3 The general methodology and basis of the technique are similar to that of Ref (2).
