Effect of impurities on radical formation in gibbsite radiolysis

Abstract

The generation and stabilization of gamma radiation-induced hydrogen atoms in gibbsite (Al(OH)₃) nanoplates is directly related to the nature of residual ions from synthetic precursors used, whether nitrates or chlorides. The concentration of hydrogen atoms trapped in the interstitial layers of gibbsite is lower and decays faster in comparison to boehmite (AlOOH), which could affect the management of these materials in radioactive waste.
