Radiolytic yield, half‐life and approximate migration distance of main radiolysis products in water. The radiolytic yield (G value) represents the number of molecules created or destroyed per 100 eV of energy deposited in the system and half‐life is the time required for a quantity to reduce to half of its initial value
