a. The radiation damage assessment shall use either the DDEF of mono-energetic protons, electrons, or neutrons calculated as specified in clause 8.5.2.1, or the TNID, calculated as specified in clause 8.5.2.2.
b. The influence of shielding in attenuating the primary particle environment and modifying its spectrum shall be analysed.
NOTE Methods for the related shielding calculation are specified in clause 6.2.
c. The influence of secondary protons, electrons and neutrons on displacement damage shall be analysed.
NOTE In many cases the analysis can conclude that their contribution is negligible, but in some circumstances secondary protons, electrons and neutrons can have an important contribution.
