A non-destructive system for determination of silver traces in air particulates collected on cellulose filters is described, based on neutron activation followed by110Ag β counting instead of the 657.7 keV γ-ray. The determination limit (for 10% confidence limit) is estimated to be about 10−9 g. The method is easily applicable to the determination of silver in cloud seeding experiments, since the filters themselves provide a consistent and fairly uniform source and samples are collected in general far from industrial areas, where the concentration of possible interfering elements in air is reasonably low.
