Parameters of Dosimetric Interest of Some Vanadium and Nickel Compounds

Abstract

Mass attenuation coefficients (μm), effective atomic numbers (Z_eff) and electron densities (N_el) of some vanadium compounds V₂O₃, VO₂, VF₃, VF₄, NH₄VO₃ and nickel compounds NiF₂, NiCl₂, NiCl₂.6H₂O, Ni(ClO₄)₂.6H₂O, NiF₂.4H₂O have been computed over a wide energy region from 10 keV to 100 GeV. In all the parameters, a similar trend is observed. All the parameters initially possesses maximum values, which decreases very rapidly upto 100 keV, then becomes almost constant upto 3 MeV and with the further increase in the incident photon energy beyond 3 MeV, values of all the parameters also increase which may be due to dominance of different partial photon interaction process in different energy regions.
