The effect of gamma irradiation on the radiofrequency dielectric properties of bovine kidney tissue has been investigated using gamma irradiator (Gs 1000), booton (7200) capacitance meter, signal generator (Lodstars SG-416013) and Dielectric cells Mathematic models of the following dielectric structural parameter, Dielectric spread parameter (), dielectric decrement () and Dielectric relaxation time (), were also developed. The mathematics models were found to be polynomial functions of degree 4,4, and 5 respectively. The coefficient of fit for dielectric decrement, relaxation time and spread parameter (), were found to be 98.2, 83.9 and 99.5, respectively. This shows that, the mathematical model can be effectively used to generate dielectric data that will facilitate the prediction of the extent of mammalian kidney tissue damage in gamma irradiation doses regime usually encountered in diagnostic and therapeutic radiology.
Key words: Gamma irradiation, spread parameter (), dielectric decrement (), dielectric relaxation time (), dielectric permittivity ().
