Counting a small number of radioactive atoms

Title of program: COUNTING FEW RADIOACTIVE ATOMS Catalogue Id: AAUS_v1_0 Nature of problem The problem is to determine the frequency function P(n) of the posterior probability that a small sample of a radioactive isotope R contains n atoms at the end of the production of R, when the counts in the subsequent counting periods are known.
