33.4 y 8 (1978Ya04) deduced indirectly using the decay of a 211At source and knowledge of the ε/α branching ratio of 211At (0.583/0.417), the emission probability of 6568 MeV α to the 569.7 keV level of 207Pb (0.58% 1), the half-life of 211At (7.23 h 2) and the total emission probability of 569.7γ fed in 207Bi ε decay (99.85%). The quoted uncertainty is statistical only, but a large syst. uncertainty can be expected. The authors also quote a value of 32.2 y 13 using disintegration rate of 211At in a purified sample measured by the means of a liquid scintillation counter and by adopting the 569.7γ to determine the decay rate of 207Bi. α measurement performed after a complete decay of 211At yielded T1/2=32.2 y 37, whereby the large uncertainty was attributed to the poor detection efficiency of gamma counting of this particular sample.
