Raman mapping of coal halos induced by uranium mineral radiation
Original language description
Using linear profilesacross the entire halos, changes in the degree of radiolytic alteration of coal matter caused by ionising radiationresulting from the decay of uranium and its daughter products, were described. Using micro-ATR-FTIR,oxidative radiolytic alteration of coal was identified in halos, with oxidisation to alcohols, ketones and carboxylgroups, which were then converted to COO− ions bound to the cations present, including UO22+. From ourdata, we conclude that the conversion of the original coal to a type of anthracite occurred during the process ofCHandCC cleavage, dehydroaromatisation of naphthenic rings and oxidation resulting in the transformationof aliphatic structures into aromatic clusters. Generally, radiolytic alteration increased the structural organisationof coal.Monte Carlo simulations of the observed radiation alteration by the ionising energy loss and non-ionisingenergy loss were performed.
