Absolute activity measurement of the electron-capture-based radionuclides.

This article is validated for 0.1 CPD Credits in Category 1. Click here to access the article. Abstract Four radionuclides with electron-capture-based decay schemes have been directly measured by a liquid scintillation coincidence extrapolation technique. 125I, 192Ir and 65Zn were measured as part of international key comparisons held under the auspices of the International Bureau …
