We postulated that the stopping power of a given chemical system to thermal-energy electrons must be practically equal to zero. Starting from this postulate we introduced a correction factor to the dividend of the logarithmic term of Bethe's equation. In addition, we redefined the parameter n, to ensure its adaptation to absorbing media consisting of a chemical compound or mixture. In this way, the total LET values and the most probable ranges of low-energy electrons in water, iodobenzene, air, methane, tissue-equivalent material, and rare gases were calculated, and the results obtained were compared with the values in the literature. © 1987.en10.1016/0168-9002(87)91114-4info:eu-repo/semantics/closedAccessArticle25501.Feb274280Q1
