Question
The carbon buried in a peat bed has about 12.5% of the Carbon-14 of modern wood. What is the age of the peat bed? Explain?
Answers
Damon
half life of carbon 14 is about 5730 years
.125 = (1/2)^n where n is the number of half lives
log .125 = n log .5
n = 3 half lives
3 * 5730 = 17,190 years old
