Abstract

Gel dosimeters are based on chemical dosimeters in which radiation induced chemical reactions occur. The addition of gelling agents such as gelatin to certain chemical dosimeters can enable these chemical reactions to be stabilised spatially, which enables the 3 dimensional distribution of the dose within the volume of the dosimeter to be determined. A gel dosimeter based on the Fricke dosimeter has been investigated. A series of measurements to characterise the Fricke gel have been summarised in this report. Progress in the development of an optical computed tomography system and associated reconstruction software is also reviewed.
