Yield of the Fricke dosimeter irradiated with the recoil α and Li ions of the 10B(n,α)7Li nuclear reaction: effects of multiple ionization and temperature

Abstract: Monte Carlo track chemistry simulations were used to investigate the effects of multiple ionization (MI) of water on the yields (<i>G</i>-values) of the ferrous sulfate (Fricke) dosimeter which was irradiated with low-energy α and lithium ion recoils from the <sup>10</sup>B(<i>n</i>,α)<sup>7</sup>Li nuclear reaction as a function of temperature from 25 to 350 °C. Calculations were performed individually for 1.47 MeV α-particles and 0.84 MeV lithium nuclei with do… Show more

“…Before considering the cellular effects of this chemical reaction, it is important to note the timescale on which these reactions occur [ 80 ]. There is a bi-phasic oxidation of Fe 2+ in solution, with an initial burst of oxidation occurring in ≈10 −8 s and maximizing at ≈10 −6 s. The first burst of Fe oxidation is the result of HO 2 • -mediated oxidation (Rxn 14).…”
