Method for high absorbed dose measurement and standardization

To establish the method for high absorbed dose measurements and standardization is important in the dose assurance of the product irradiation. The experiments using OAEP's cobalt-60 source including the homogeneity testing and the dose rate determination were employed by Fricke dosimeter. The cerium sulfate solutions were calibrated against the Fricke's dose rate, and the achieved G-value was within the possible range. The opti-chromic dosimeters were used as the cross-check of the locally calibrating system and the standard laboratories; the National Bureau of Standards (NBS), U.S.A. and the Boris Kidric Institute of Nuclear Science, Vinca, the results were within acceptable range
