How to solve half life equations geology
WebHalf life of a radioactive substance is calculated by measuring the time it takes for its activity to decrease by half. A practical way to estimate half life is to measure the activity … WebMay 22, 2015 · The uncertainty on the corrected activity increases linearly in time (via td and tm, if tm < T1/2) and the propagation factor is significant for time periods of comparable magnitude as the half-life. With every 0.1% uncertainty on the half-life, the uncertainty of the activity increases by 0.07% per half-life.
