Effects of Ionizing Radiations on the Resistances of Locally Available Brand of Ceramic Resistors

Abstract

In this research work the resistances of ceramic resistors ranges from, low, medium and high  were observed for cumulative doses of gamma radiation of Co-60 and 6Mev electrons. The resistors post exposure to ionizing radiations have showed fluctuating behavior in their resistances for different cumulative doses.  It is observed that the radiations of Co-60 and 6 Mev electrons have shown almost the same pattern of responses. Low range resistances have shown increment in its resistances after the very first dose of 10Gy. Medium range resistances initially showed fluctuating behavior, but the overall the resistance was observed to be declined. The high range resistances have also shown fluctuating behavior with two peaks for different cumulative doses of Co-60 photons and 6Mev electrons, then attained the resistance almost the same as initial unirradiated sample.
