Abstract
THE oxidation of ferrous ions in dilute sulphuric acid solution by X- and γ-radiation has attracted attention since the work of Fricke1,2 as a possible method of integral dosimetry for aqueous media3. A study has now been made which confirms that the rate of oxidation with dose is essentially independent of the concentration of ferrous ions in the region 103 to 10-4 M, and which also shows that this rate is maintained independently of the wave-length of the radiation over a much wider range of wave-length than has hitherto been used in studies of this type.
