Abstract: | A detailed study of the influence of barium on the electrodeposition of226Ra was made using two different procedures. High yields (80–90%) were attained when the amounts of barium were not very significant. However, the226Ra yields fell drastically for amounts slightly greater than 0.10–0.15 mg of Ba, according to the electrodeposition procedure. Samples containing trace amounts of barium less than 100–150 g can thus be treated with no barium-radium separation being required.210Po was also deposited, although practically no influence of barium on the Po plating was observed. The225Ra resolution rose uniformly (25 to 55 keV) as the amount of barium rose up to 1 mg. These resolutions allow one to make a direct accurate determination of226Ra as well as an indirect determination of224Ra and223Ra via measurement of their daughter products. |
