Abstract: A low-power wireless ionizing radiation measurement system is present that is intended to be used in a wearable dosimeter for occupational radiation monitoring. An apparatus is provided comprising a switching interface, wherein the switching interface alternates between a first switching state and a second switching state. In the first switching state, a radiation-sensitive metal oxide semiconductor capacitor (MOSCAP) is coupled to an external biasing source. In the second switching state, the radiation-sensitive MOSCAP is coupled with reversed polarity relative to the first switching state to a capacitive readout circuit to thereby allow for high-resolution real-time electronic measurement of a radiation-induced capacitance response.
