Abstract
A new chemical dosimeter is descr. that provides a means of measuring the H2O2 formed in gamma-ray "hot spots" or in ionizing particle paths. This dosimeter, consisting of FeSO4 and CuSO4 dissolved in 0.01 N H2SO4, is sensitive only to H2O2 generated by the ionizing radiations. The effect of the free radicals, HO2 and OH, on the FeSO4 is cancelled by the CuSO4. GFe +++ is 0.66 [plus or minus] 0.02 for gamma-rays and is 2.0 [plus or minus] 0.2 for B10 (n,a)Li7 recoils. The major features of the mechanism of the reaction and the general dosimetry of mixed gamma-ray and alpha-ray radiations are indicated.Keywords
