Abstract
A method for measuring half-lives with Geiger counters which is independent of counting losses is described. Foils which have been irradiated for various times are counted after a lapse of time adjusted to make the counting rates of the foils the same. Saturated activities of the foils will be different if an incorrect value of the decay constant has been assumed. Equations are given for obtaining a more correct value of the decay constant. The method is illustrated by data on the 54-minute period of indium.Keywords
