Description
Summary:In this work, we have studied the behavior of crystalline ferrous ammonium sulfate (FAS) under gamma irradiation. The doses studied ranged from 33.5 to 270 kGy. The purpose of this study is to explain the setup, measurement, and reporting procedures for using FAS as a dosimeter. The results obtained in the present study show that this salt very easily gave reproducible results, a linear response, as well as, simple sample preparation and reading. The irradiation temperature and dose rate in the response of the iron salt were found to have slight influence. Any storage time up to 18 months resulted in a 36% decrease in the response. The variation in the response obtained for short periods of storage is negligible for this application. Due to the properties of the FAS system also can be use as transfer dosismeter.
