ANALYTICAL TECHNIQUES FOR FASTER CALCULATION OF THE LIFE EXTENSION ACHIEVED BY ELIMINATING A PROLONGED RADIATION EXPOSURE

摘要

The life extension achieved by a safety scheme that reduces or eliminates a prolonged radiation exposure is a necessary parameter for calculating the Judgment-or J-value,which enables the scheme's worth to be measured on a common,objective scale against which health and safety spend across all economic sectors can be assessed.The life-expectancy calculation for radiation exposure is necessarily complex because of the long and stochastic incubation periods associated with radiation-induced cancers.Analytical methods are presented to reduce the size of this calculation approximately a hundredfold.This renders the J-value assessment much quicker and easier for new safety systems that may be considered for nuclear plant.
