WebRadiation treatment using gamma-rays was investigated in order to reclaim the secondary effluent from a sewage treatment plant. The radiation treatment reduced BOD by 85% irrespective of absorbed dose, and the removals of COD, TOC and color were up to 64%, 34% and 88%, respectively, at a dose of 15 kGy. WebIn this paper, the gamma irradiation effects on the structural and optical properties of N-doped 4H-SiC (n-4H-SiC) is presented up to a cumulative gamma radiation dose of 1500 kGy. The studies showed marginal and inconsistent variation in the c- and a-axis lattice constants of 4H-SiC due to the accumulation of gamma-induced defect states. hca1 forms
