The half-life of C-14 is 5730 years. A sample that has decayed for three half-lifes is 3 x 5730 years or 17,190 years old.To determine how much C-14 is in a sample, radiation detectors count the number of BETA particles released by radioactive decay.The result is called the ACTIVITY (disintigrations per minute per gram of carbon--dpm/g).he calculator has the Half-life of C-14 (5730 years) built-in and allows you to convert fractions of Half-lives to years. For example a sample with only 90% residual C-14 is about 0.16 HL old, which from the calculator is over 900 years.
