The world-wide average strontium-90 content of man was about 0.12 micromicrocurie per gram of calcium (1/10,000 of the maximum permissible concentration) in the fall of 1955. A few values as high as 10 times the average have been obtained. This value

A new determination of the half-life of ${\mathrm{Pb}}^{210}$ has been made by the geological method. Pb${\mathrm{Cl}}_{2}$ extracted from uranium minerals in secular equilibrium was used to calibrate a thick-source scintillation counter for ${\mathr

The ages from the isotopic ratios Pb206U238, Pb207U2 and Pb207/Pb206 do not agree with each other for a large fraction of the minerals studied. Many of these anomalous ages cannot be explained by radon leakage or errors in lead isotopic composition,
