The half-life of the alpha emitter, Pu 236, was measured by a direct decay method. Corrections were applied for the alpha-emitting daughters of Pu 236. The results of three sets of data were: 2·855 yr, s = 0·009 yr; 2·817 y, s = 0·04 yr; 2·836 yr, s = 0·021 yr....
Abstract The half-life of 238Pu has been measured by determining its rate of growth from 242Cm. The weighted average of two determinations is 86·41 years, with an estimated error of 0·3 year. Previous article in issue Next article in issue Recommended articlesCited...

A half-life value of (3.742+/-0.024) × 10yr is obtained using the half-life of Pu as 24110 yr. The value obtained using the half-life of Pu as 87.74 yr is (3.766+/-0.025) × 10yr. The average of these two independent sets of experiments leads to a half-life value of Pu as...
