摘要：

In aggressive industrial processes, power plants and radioactive waste storage places it is important to monitor the level of radiation. To minimise personnel exposure a wireless system is presented, where thick film MgO and CeO2 capacitors with Ag interdigitated electrodes were used as prototype radiation sensors. MgO and CeO2 thick films were monitored during radiation exposure using a capacitance to digital converter system. A monotonic increase in the values of capacitance from 1.493 pF to 1.537 pF was recorded for MgO as a result of 32.55 mGy gamma-dose of A(137) CS gamma-source. Counterpart CeO2 films were shown to be less susceptible to radiation. Moreover, the response of MgO sensor was monotonic over the whole range.
