Abstract

With the development of digital x-ray sensing devices, demand for stable and highly sensitive material is continuously increasing. Various solid state materials have been discovered like mercuric iodide, lead iodide, potassium di chromate etc. These materials are used both in single crystal form and polycrystalline form. Most of the materials are found to have limited stability. In search of highly stable material, composite materials using polymers are searched. In present study cadmium iodide in PMMA is subjected to the study for their X-ray sensing properties. For these their electrical conductivity measurements were made both in absence and in presence of radiations (X-Rays and low intensity Gamma Rays). Results, obtained are analyzed in the light of photocurrent generated by high energy radiations. These composites are found to have high efficiency and stability for X-ray sensing. However x-ray switching response is limited.
