Webtime of measurement (half-life >> time of measurement). Thus, a direct measurement of the activity for a known sample size yields the decay rate constant, from which the half-life can be determined. (See Equations 2 and 3.) B. Half-Life of a Short-Lived Radioisotope Cesium-137 is a radioactive isotope with a half-life of 30.2 years.
Webmean life, in radioactivity, average lifetime of all the nuclei of a particular unstable atomic species. This time interval may be thought of as the sum of the lifetimes of all the individual unstable nuclei in a sample, divided by the total number of unstable nuclei present.
