Abstract
The oxidation of ferrous ion in ferrous-cupric acidic aqueous solution by Co-60 gamma-rays was studied in order to find a good chemical dosimeter for high doses. Consequently, it is found that the non-treated solution containing the 10−3M cupric ion is useful for this purpose, for this amount of cupric ions is sufficient to suppress the effect of oxygen, and that the G-value of the ferrous-cupric system is dependent on the composition of the solution. The suppression can be explained by the scavenging of the HO2− ion by cupric ions. Furthermore, some discussions regarding the system are given in the present paper.
