Hello
EM-ENERGY includes energy depositions from electrons (including delta
rays) positrons and photons. It does not include ion recoils. It does not
include "continuous" , meaning below delta-threshold, ionization energy
losses.
NIEL: maybe you can have a look to the slides from 8 onwards in the
Advanced materials lectures in the latest advanced fluka course
