Device for detecting ionising radiation and dosimeter comprising thereof

A device for detecting ionising radiation comprising:

• a first set with a plurality of primary floating gate sensors with a cumulative response proportional to a received ionising radiation, wherein each primary floating gate sensor of the plurality of primary sensors is independent of each other;
• a second set with a plurality of secondary floating gate sensors with a cumulative response proportional to a received ionising radiation, wherein each secondary floating gate sensor of the plurality of secondary gate sensors are independent of each other;
• wherein each primary sensor comprises a first floating gate capacitance for having a sensitivity to ionising radiation above a first threshold;
• wherein each secondary sensor comprises a second floating gate capacitance for having a sensitivity to ionising radiation above a second threshold, the second floating gate capacitance being different to the first floating gate capacitance;
• wherein the second threshold is lower than the first threshold, whereby the first set is configured to detect ionising radiation in a first range and the second set is configured to detect ionising radiation in a second range, wherein the first range is lower than the second range.
