A rapid non-destructive method for the specific analysis of Ag in coins has been developed. Rather than coins being placed in a nuclear reactor, which produces a long half-life isotope, they are irradiated with a convenient Pu-Be neutron source which induces radiation that effectively lasts less than 15 mins. The advantages are that borrowed coins can be immediately returned, results can be checked by series of repeated analyses, and Ag content only is analyzed. The effectiveness of 3 possible equations for calculating Ag content from the results is examined. The best gives values generally accurate to within ± 2%. -- AATA
