WebTo determine the absolute age of this mineral sample, we simply multiply y (= 0.518) times the half life of the parent atom (=2.7 million years). Thus, the absolute age of sample = y * half-life = 0.518 * 2.7 million years = 1.40 million years.
WebHalf-life is a measure of the time it takes a radioactive sample to decrease its mass or quantity by half and, among other things, its danger.
