Samples were fabricated using the thick film screen-printing technique. All devices were exposed to a disc-type 137Cs source with an activity of 370 kBq. They showed an increase in the values of current with the increase in radiation dose up to a certain level. Performance parameters of the devices, such as sensitivity to ¦Ã-radiation exposure and working dose region, were found to be highly dependant on the composition of the materials used. %K Nickel Oxide %K Thick Films %K Gamma Radiation %K Pn-junction %K Interdigitated Electrodes %U http://www.mdpi.com/1424-8220/3/6/176
