Described is a radiation dose calculation algorithm based upon the output of a radiation dosimeter including multiple sensor devices (including one or more passive integrating radiation sensors and optionally, a MEMS accelerometers, a wireless transmitters a GPS, a thermistor, or other chemical, biological or EMF sensors). The algorithm is used to convert the sensor output into dose values used to assess the exposure of personnel to ionizing radiation. Sensor output patterns are matched to stored empirically generated sensor outputs thru weighting and optimization calculation processes to determine personnel doses. Algorithm outputs can include personal dose equivalents, radiation types, radiation energy and radiation source identification. Dose calculations can be optimized for specific applications, and matched to different sets of measured data without changing the underlining software calculation programs.

Described is a radiation dosimeter including multiple sensor devices (including one or more passive integrating electronic radiation sensor, a MEMS accelerometers, a wireless transmitters and, optionally, a GPS, a thermistor, or other chemical, biological or EMF sensors) and a computer program for the simultaneous detection and wireless transmission of ionizing radiation, motion and global position for use in occupational and environmental dosimetry. The described dosimeter utilizes new processes and algorithms to create a self-contained, passive, integrating dosimeter. Furthermore, disclosed embodiments provide the use of MEMS and nanotechnology manufacturing techniques to encapsulate individual ionizing radiation sensor elements within a radiation attenuating material that provides a “filtration bubble” around the sensor element, the use of multiple attenuating materials (filters) around multiple sensor elements, and the use of a software algorithm to discriminate between different types of ionizing radiation and different radiation energy.

A low-power wireless ionizing radiation measurement system is present that is intended to be used in a wearable dosimeter for occupational radiation monitoring. The detector element is a custom MOS capacitor that traps holes in proportion to the amount of ionizing radiation incident upon the detector, thus permanently causing a lateral shift in the CV-curve (toward more negative threshold voltage). The circuit measures the capacitance value of several redundant sensors at a given voltage in the depletion region, records this value over time and occasionally transmits the stored values to a base station. From the change in capacitance, the dose that has been delivered can be determined.

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.

A method and apparatus is disclosed for differentially altering the radiation response across multiple MOSCAP sensors by placing different thin gate materials with different atomic numbers on a series of MOS-based radiation sensors. The secondary electrons created in high-atomic weight materials (such as gold) at lower incident photon energy levels enable a tissue equivalent radiation response and radiations source identification/differentiation. This is a desirable alternative to using filters with different coefficients across a series of MOSCAP radiation sensor which will attenuate the signal and degrade the device form factor. The method and apparatus disclosed achieves the same functionality but with inherent gain instead of attenuation, thus increasing sensitivity. This will improve the minimum resolvable dose for x-rays and low-energy gammas (high-energy gammas will remain the same), and produces a response that can distinguish the energy level of incident radiation photon.
