Various possible sources of Po for industrial use are discussed and reasons for selection of active lead salts for this purpose are given. Methods of measurement of the amounts of Po present on plated metal foils and in electrode alloy are described. The RaD/Pb ratio was found to vary from 1.2×10-8 to 1.9×10-8 for various samples of active lead from the Great Bear Lake region. Methods for extraction of Po from active lead salts are discussed and a large scale plating method is described. Results of experiments on the rate of Po‐plating from boiling solutions of active lead salts as related to the acid concentration, exposed foil area, foil composition, etc., are presented. Chemical methods for producing soluble active lead salts are described. A method of introducing Po into electrode alloy is described. In a typical experiment, it was found that 94 percent of the Po introduced into the melt was retained in the final alloy. Contact radiographs of electrode alloy samples showing the affect of various heat treatments and surface condition are presented.
