Summary

Tokaimura criticality accident is considered a precious material for nuclear emergency response study. The study on dose assessment and management methods discusses how to manage termination of the criticality accident at work. Based on measurements from around 40m to 100m, a re-evaluation of the dose was made, with reevaluated doses matching with a degree of accuracy of 60% to 80% compared with individual doses. The study validates doses using log-log plots and semi-log plots for the distance from the source approximately 100m and further attenuation. For high doses of neutrons, dose constraint assessment should consider the annual dose limit for workers, dose received other than the same work, and measurement error. Using 10mSv, half of the annual limit 20mSv, as a dose reference, work can be safely managed. The study summarizes the valid range of log-log plots for intense neutron dose estimation.
