El-Ghossain [14] used SRIM-2008 to study the interaction of He ions with body tissues and bodily fluids at the 10 keV–10 MeV ion energy range.
Mei et al. [16] varied doses for He–BFO irradiation, resulting in larger ferroelectric coercive fields as doses were increased.
Tyagi et al. [5] have investigated SO₂ gas detection efficiency of SnO₂ thin film sensors with heavy Ni7+ion irradiation.
Singh et al. [17] have studied the tuning of defects induced photoluminescence in Ni-irradiated and Au-irradiated ZnO films.
El-Ghossain, Calculations of Stopping Power, and Range of Ions Radiation (Alpha Particles) Interaction with Different Materials and Human Body Parts, Int.

Compacting pressure affects significantly the value of specific electrical resistivity, what in turn has a substantial effect on eddy current loss (dominant at increased excitation frequencies), as discussed previously by Lefebvre et al. [11] and Saito et al. [12].
De Wulf et al. [16] have considered the possibility to introduce a correction factor for conductivity.
A similar homogenization scheme, but for a spherical particle shape, has been advanced by Taghvaei et al. [17].
