Radioactive Equilibrium Time
Publication: Journal of the Sanitary Engineering Division
Volume 92, Issue 6
Abstract
The use of radioisotopes in research and stream survey work necessitates the collection of a large number of samples that may contain radioisotopes which yield radioactive daughters. When analyzing such samples, it is necessary to allow the samples to reach equilibrium. The time required to reach equilibrium, secular or transient, can be calculated from basic nuclear physics equations. However, when multiple calculations are required, the table and figures presented are useful in providing a quick, accurate answer.
