Abstract |
A tentative reference method for the measurement of gross alpha and gross beta radioactivities in environmental waters is described. Samples of environmental water sources are collected, preserved by acid treatment, and aliquots of the samples are evaporated to dryness in a counting dish and counted for alpha and beta activity. Counting efficiencies for sample aliquots are read from curves prepared from counting data of prepared standards, using a known quantity of cesium-137 and 0-10 milligrams of evaporated water dissolved solids per square centimeter of counting dish area for gross beta, and a known quantity of americium-241 and 0-5 milligrams of evaporated water dissolved solids per square centimeter of counting dish area for gross alpha. Results are reported in pCi/liter. |
