The distribution of half-lives (seconds) expressed as logarithm (base 10) for over three thousand radionuclides is examined. The best fit normal distribution (mean 1.58, standard deviation 2.38) is shown. The fit while good, tends to underestimate the number of radionuclides at both the high and low ends of the distribution. Some implications are noted.
