Radiolytic formation of tribromine ion Br3− in aqueous solutions, a system for steady-state dosimetry

Several aqueous solutions containing high concentrations of bromine ion were gamma-irradiated and the radiolytic yield of the formed tribromine ion, Br3−, was determined. Br3− can be stabilized under certain conditions and its formation yield can be very high and constant over a wide range of irradiation dose. The possibility to use that system for steady-state dosimetry is discussed.
