The ZnS crystal was irradiated by electron beam with an energy of 2 MeV and fluences from 0.5×1017 electron/cm2 to 1.5×1017 electron/cm2 . The initial structure of ZnS is in line with the cubic phase (sp.gr. F-43m), which is stable when irradiated with the electron fluences up to 1.5×1017 electron/cm2 . An increase in the size of crystallites from 19.9 nm to 23.1 nm, a decrease in the dislocation density from 2.53×1011 cm−2 to 1.87×1011 cm−2 , and a change in microstrain from 7.11×10−3 to 6.10×10−3 are observed with an increase in the electron fluence up to 1.5×1017 electron/cm2. It has been established that electron irradiation leads to decrease of the ZnS single crystal band gap which is associated with an increasing of the crystallites size and a changing of the lattice parameter. The microhardness of the ZnS single crystal increase to 8% due to the growth in the size of nanocrystallites as a result of electron irradiation
