OSTI ID:7330404
The preparation and procedure for the use of a Fricke dosimeter are described. The dosimeter is based on the process of oxidation of Fe/sup 2 +/ to Fe/sup 3 +/ by x or ..gamma.. rays or high-energy electrons. The method can be accurately used for absorbed dose determination in the range from 0.2 x 10/sup 4/ to 4 x 10/sup 4/ rd, using a spectrophotometric determination of the Fe/sup 3 +/ concentration. The system is extremely sensitive to organic inpurities even in trace amounts. The precision of the method is +-1.0 percent and the accuracy is +-2.0 percent. (BLM)
