How to calculate radioactive dating
Web3 okt. 2000 · A formula to calculate how old a sample is by carbon-14 dating is: t = [ ln (Nf/No) / (-0.693) ] x t1/2 t = [ ln (Nf/No) / (-0.693) ] x t1/2 where ln is the natural logarithm, N f /N o is the percent of carbon-14 in the sample compared to the amount in living tissue, and t 1/2 is the half-life of carbon-14 (5,700 years). WebGeologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms."
