The statistical analyses were made with regard to the distribution of annual radiation doses of the workers in the Japan Atomic Energy Research Institute (JAERI) in order to clarify the characteristics of exposure pattern and to examine the goodness of fit of the data to the theoretical probability distributions.The following conclusions were obtained.1) A log-normal distribution provide a good fit to the annual dose distributions.2) A double exponential distributions provide a good fit to the distributions of annual maximum dose.3) A log-normal distribution provide a good fit to the distributions of the ratio of annual maximum dose to average one.4) The annual maximum dose arranged in the order of their magnitude is expressed by an exponential function and the dose is decreased to 1/e with every eleventh.
