Carbon 14 has a half-life of 5.73*10^3 years. C-14 in a piece of living bone has an activity of 14 decays per minute per gram of bone. If a bone found under a parking lot in San Diego has an activity of 3.5 decays per minute per gram of bone, then approximately how long has it been since the bone was alive?

The answer is not 13657.8
A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.2 kg sample of carbon from the wood has an activity of 1660 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y.

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...

Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a one-gram sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour. A one-gram sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed? A. 1/8 B.3 C.113 D.8 Approximately...
