摘要

40K的长半衰期和在环境中无处不在的存在使得这种放射性核素在从γ射线光谱到地球中微子的任何放射性背景研究中都有重要的贡献，并作为矿物地质年代测定的辅助手段。最近40K的新衰变数据测量激发了对衰变数据的大量重新评估。建议新的半衰期和分支比，以及天然钾样品的特定活性。还评估了其他有关的原子和核数据，并在DDEP网站上提供了一套完整的这些建议数据。

DDEP evaluation of 40K decay

The long half-life and ubiquitous presence of ⁴⁰K in the environment makes the contribution of this radionuclide significant in any studies of the radioactive background from γ-ray spectrometry to geoneutrinos, and as an aid in the geological dating of minerals. Recent new decay-data measurements of ⁴⁰K have motivated this substantial re-evaluation of the decay data. New half-life and branching ratios are recommended, as well as specific activities for natural potassium samples. Other relevant atomic and nuclear data have also been assessed, and a complete set of these recommended data made available on the DDEP website.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
