  Several studies have confirmed visible light and ultraviolet emission during
water molecule radiolysis.However radiofrequency (RF) emissions have been
scarcely investigated.This simulation study has revealed that the gamma
radiolysis of water creates excited hydrogen atoms which emit radio
recombination Lband (1 GHz to 2 GHz) radio waves of sufficient strength that a
radio-imaging device can detect.The physical and physicochemical stages of
radiolysis of water have been modeled via application of Monte Carlo simulation
techniques up to 1ps from the onset of gamma photon interaction with water
molecules.
