A new determination of the half-life of Pb/sup 210/ was made by the geological method. PbCl/sub 2/ extracted from uranium minerals in secular equilibrium was used to calibrate a thick-source scintillation counter for Po/sup 210/ alpha particles. Using this calibration the absolute activity of Po/sup 210/ in partial equilibrium with a known number of Pb/sup 210/ atoms prepared from the decay of a measured quantity of radon was determined. From these data a half life of 21.4 plus or minus 0.5 years was obtained for Pb/sup 210/. (auth)
