Question

Assuming that the time that it takes a radioactive nucleus to decay is exponentially dis-

tributed, nd the

relationship between the rate of decay λ and the half-life t1/2, which is the

time at which the probability of decay is equal to 1/2. Given that the half-life of carbon-14 is

5730 years, approximately what proportion of a sample of carbon-14 will remain after 44,000

years?
