A nondestructive neutron activation technique for the simultaneous direct determination of chlorine, bromine, and iodine in
silver halide mixtures is described using a252Cf neutron multiplier (CFX). About 5–50 mg of sample are used. The analysis is semiroutine, without the need for a monitor
included with each sample since the flux stability and reproducibility are within ±1%, decaying only with the 2.65 year half-life
of252Cf. The precision and accuracy are counting-statistics controlled and are generally ±1% RSD or better. The method offers an
attractive alternative to existing chemical and instrumental methods for these determinations in silver halide mixtures because
it has the potential for providing reasonably rapid analyses with good precision and accuracy.
