ASTM D7283 - 2017 Standard Test Method for Alpha and Beta Activity in Water by Liquid Scintillation Counting

American Society for Testing and Materials - 2017.- 13 p.
This test method covers the measurement of gross alpha- and beta- activity concentrations in a homogeneous water sample. It is applicable to alpha emitters with activity concentration levels above 0.11 Bq/L and beta emitters with activity concentration levels above 0.15 Bq/L. This test method is not applicable to samples containing radionuclides that are volatile under conditions of the analysis.
This test method may also be used for the direct measurement of gross alpha- and beta- activity concentrations in homogeneous water samples with alpha emitter activity concentration levels above 1.8 Bq/L and beta emitter activity concentration levels above 3.7 Bq/L.
