OSTI ID:5549850

The Fricke dosimetry is used for accurate measurement of the absorbed dose in water irradiated with x- or gamma rays or high-energy electrons. The method is based on the process of oxidation of ferrous to ferric ions by ionizing radiation and can be used accurately for absorbed dose determination in the range from 0.2 x 10/sup 4/ to 4 x 10/sup 4/ rad, using spectrophotometric measurement of the ferric ion concentration. The method covers the preparation and procedure for the use of the Fricke dosimeter and includes a discussion of interferences, apparatus, reagents, calibration and standardization, dosimetry procedure, calculation, precision, and accuracy.
