The final product of the gamma radiolysis of anhydrous cesium tris(oxalato) ferrate(III) has been identified by Mossbauer spectroscopy as Cs2Fe(ox)2. The radiolytic decomposition proceeds as a first-order process due to the original compound depletion and to the radiolytic stability of the ferrous compound. Lamb-Mossbauer factors measurements indicate that the recoilless fractions of the iron species arc practically unaffected by thc radiolysis.
