Abstract
THE action of X-rays and gamma-rays on a solution of ferrous sulphate in 0.8 N sulphuric acid has been studied by a number of investigators1. The iron is oxidized to the trivalent state, and the amount of trivalent iron is proportional to the radiation dosage. For this reason the ferrous sulphate solution has been used for radiation dosimetry. The amount of ferric ion is usually measured colorimetrically, photometrically or volumetrically. In the present investigation, some experiments have been carried out to measure the ferric ions radiometrically in order to increase the sensitivity of the dosimeter.
