Radioactive atoms: Auger-Electron, α-, β, γ-, and X-Ray Data

Nuclear Data Sheets for A = 137☆

Half-lives have been measured by direct decay for 18 radionuclides. The method of least squares was used to obtain the best straight-line fit to the data. The observed half-lives are 87.9 ± 0.3 d f...

Half-life determinations by direct decay

Discrepant data sets are encountered in many areas of science and technology. Several objective data evaluation procedures have been suggested to detect, adjust or eliminate discrepant data. These techniques are reviewed, and assessed in terms of the published half-life data of 137Cs. A new three-step data evaluation procedure is also presented together with results of applying this method to half-life data for 90Sr, 137Cs, 154Eu and 252Cf.
