Description

Liquid scintillation counting (LSC) has been proposed for the determination of the gross alpha and beta activities of aqueous samples because of its simplicity and low associated costs. In this paper, protocols for gross alpha and beta activities determination of the samples of waste water from the discharges of radiochemical laboratories and of the water samples from underground low-level waste repository monitoring wells are described. Lower limits of detection as low as 30 mBq.L-1 for gross alpha and 90 mBq.L-1 for gross beta activities are achieved for 10 000 s measurement of a sample produced by concentration of 1 L of the ground water.
