A method is described for recovering and purifying 241Am from lightning-conductors and smoke detectors. The method is based on the precipitation of silver, as AgCl, the main impurity, and extraction of americium with TBP. Further purification with ion-exchange resin is also used. The results have shown that by this method the americium is obtained with high purity.
