Various iron compounds have been irradiated with gamma-rays of cobalt-60. The foreign-charge states of the irradiated compounds were confirmed by means of Mössbauer spectroscopy. The results showed that high-spin iron(III) compounds with large conjugated molecules and low-spin iron(II) compounds are insensitive to γ-radiations. However, iron(III) compounds with carboxyl groups or reducing ligands and low-spin iron(III) compounds are sensitive to γ-radiations. Further, FeCl<SUB>2</SUB>·4H<SUB>2</SUB>O was found to be insensitive to radiation up to a total exposure dose of 10<SUP>9</SUP> R, in contrast to other ionic iron(II) compounds.
