Inclusion of Radiation Environment Variability in Total Dose Hardness Assurance MethodologyVariability of the space radiation environment is investigated with regard to parts categorization for total dose hardness assurance methods. It is shown that it can have a significant impact. A modified approach is developed that uses current environment models more consistently and replaces the design margin concept with one of failure probability.
