Influence of X-Rays on some electrical properties of the bovine vitreous humour

Abstract

In this study, the influence of x-rays on the ionic properties of the vitreous humour of the bovine eyes has been investigated. Each vitreous sample studied was divided into three parts with two parts x-irradiated with a skin dose of 4.43 mGy and 140.15 mGy respectively, while the third part served as a non-irradiated control. Measurements of ionic conductivity, pH and bulk electric potential were made on the irradiated and non-irradiated samples at varying temperatures from 5oC to 45oC in order to study their temperature dependence. It was observed that high radiation dose significantly altered the temperature distribution of the ionic content of the vitreous humour. The possible contributions of the observed physico-chemical changes on the structure and charge distribution in the vitreous body have been discussed.
