It is known that the ratio of `.^(14)C` to `.^(12)C` atoms in living beings and atmosphere is a constant. In one experiment it was found that the radiocarbon activity of a living thing is 16 disintegration per minute per gram of carbon content. Find the ratio of `.^(14)C` to `.^(12)C` atoms in your body. Half life of beta decay of `.^(14)C` is 5760yr=`0.03xx10^(9)` minute.

Text Solution

Verified by Experts
