Half-Lives of Long-Lived alpha Decay, beta Decay, Electron Capture Decay, Beta Beta-Decay, Proton Decay and Spontaneous Fission Decay Nuclides

摘要

In his review of radionuclides for dating purposes, Roth noted that there were a large number of nuclides, normally considered ''stable'' but which are radioactive with a very long half-life. Roth suggested that I review the data on the half-life values of these long-lived nuclides for the 2001 Atomic Weights Commission meeting in Brisbane. I provided a report, BNL-NCS-68377, to fulfill Roth's request. Peiser has now made a similar suggestion that I review these data for our next Commission meeting in Ottawa for their possible inclusion in our Tables. These half-life values for long-lived nuclides include those due to various decay modes,(alpha)-decay,(beta)-decay, electron capture decay,(beta)(beta)-decay, proton decay and spontaneous fission decay. This data review (post Brisbane) provides an update to the recommendation of the 2001 review.
