(a) This method covers the measurement of gamma radioactivity of industrial water and industrial waste water. It is applicable to gamma emitters in the energy range above 0.1 Mev and in the concentration range of 10−2 to 10−5 microcuries per milliliter of radioactively homogeneous water. (b) The method can be used for either absolute or relative determinations. In tracer work, the results may be expressed by comparison with an initial concentration which is taken as 100 per cent. For radioassay it may be expressed in terms of a known isotopic standard if the radionuclides concerned are known or it may be expressed arbitrarily in terms of some other standard such as cesium-137. General information on radioactivity and measurement of radiation has been published.
