Abstract

An instrument used to detect, and measure radiation dose is called radiation dosimeter. However, it should be reasonably sensitive to irradiation exposure, chemical transformation yield (expressed as G-value) must be sufficiently high, adequate reproducibility, and having stability of chemical solution before and after irradiation is called ideal dosimeter. A dosimeter meeting all these basic requirements is referred as “Fricke dosimeter” proposed a chemical dosimeter based on oxidation of ferrous ions in acidic aerated medium. It had maximum stability and reproducibility and most widely accepted as a standard in measurement of radiation dose. The range of Fricke dosimeter at 304 nm is 4 to 40 K rad. In this research work, absorbance efficiency and change in conductance of Fricke dosimeter has been estimated when we change the concentration of salt. Cesium CS-137 source has been used as gamma radiation source. The change in absorbance and electrical Conductivity verses time was measured individually.
