Description:
An interlaboratory collaborative study was conducted to test a procedure for the measurement of gamma emitters in drinking water. Thirty-two laboratories participated in the study. Four reference water samples containing three or all four of the gamma emitters, cobalt-60, ruthenium-106, cesium-134 and cesium-137, at concentrations ranging from 6 to 400 pCi/l, were analyzed in the study. Except for ruthenium-106, the test procedure was shown to provide adequate sensitivity of measurement for the radionuclides analyzed, as required by the National Interim Primary Drinking Water Regulations (NIPDWR), without preconcentration of the radionuclides from the samples.
