A gas-free water subjected to low-LET gamma rays yields almost no radiolysis products and sustains an equilibrium with their low concentration. High-LET alpha radiation produces larger amounts of radiolysis products.
When subjected to low-LET gamma rays, a gas-free water does not produce significant radiolysis products and remains in equilibrium with these small amounts. In contrast, high-LET alpha radiation leads to the formation of larger quantities of radiolysis products.
