Method Name:
Gross Alpha and Beta in Water. Official Name: Gross Alpha and Beta in Water

Description:
Aliquots equivalent to 100 mL for alpha and 250 mL for beta are transferred to plates and planchets for counting. Average salt contents are used in the calculation to correct for self-absorption. Self-absorption of alpha and beta particles affect counting efficiencies and must be taken into account and can be done by determining individual absorbers weights. The reference nuclide for alpha activity is Pu-239 and for beta activity Cs-137.

Scope:
This procedure is applicable to the measurement of gross alpha and beta activities in 500-mL water samples that have acidified and evaporated to 10 mL.
