RADICAL YIELD MEASUREMENTS IN IRRADIATED AQUEOUS SOLUTIONS. II. RADICAL YIELDS WITH 10.9-Mev DEUTERONS, 21.3- AND 3.4-Mev ALPHA PARTICLES, AND B(n,/cap alpha/) Li RECOIL RADIATIONS
Solutions containing ferric sulfute, cupric sulfate, and formic acid in 0.01 N sulfuric acid have been irradiated with ionizing radiations of high LET, and the yields of products measured. Information has thus been obtained concerning the effect on the yield of free H and OH radicals of increasing concentration of radical scavengers, and increasing LET of the incident radiation. Measurements have also been carried out of the yield of ferric ion in aernted and deaerated ferrous sulfute solutions in 0.01 N and 0.8 N sulfuric acid, induced by similar types of radiation. Striking departures are observed from the predictions of simple theories based on homogeneous kinetics which have proved adequate in interpreting the effects of gamma -rays on the same systems. It is concluded that with radiations of high LET even the secondary stages of the reaction mechanism take place in track zones in which the concentrations of the intermediate chemical species are changing rapidly with time.
