  • ASTM D3454 - 11 standard test method for radium-226 in water

    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. Although primarily utilized on a water medium, this technique may be applicable for the ...

  • ASTM D516 - 11 standard test method for sulfate ion in water

    The determination of sulfate is important because it has been reported that when this ion is present in excess of about 250 mg/L in drinking water, it causes a cathartic action (especially in children) in the presence of sodium and magnesium, and gives a bad taste to the water. 1. Scope 1.1 This turbidimetric test method covers the determination of sulfate in water in the ...
