Patent ID: 7157715

Claim:
A dosimeter for measuring radiation and for providing a dose output, the dosimeter device comprising, a detector for detecting the radiation and for providing a detected charge dose pulse, the detector generating a sequence of detected charge dose pulses for the radiation, an integrator for integrating the detected charge dose pulses by preintegrating each of the detected charge dose pulses prior to the detected charge dose pulse reaching a dose pulse threshold and by postintegrating each of the detected charge dose pulses after the detected dose pulse reaches the dose pulse threshold, the preintegrating and postintegrating for providing an integrated dose pulse for each of the detected charge dose pulses reaching the dose pulse threshold, the integrated dose pulse being generated each time one of the detected charge dose pulses reaches the dose pulse threshold, the integrator providing a sequence of integrated dose pulses corresponding to a respective sequence of detected charge dose pulses reaching the dose pulse threshold, and a summer for summing the sequence of integrated dose pulses into a total dose level, the summer for comparing the total dose level to a total quantum threshold, the summer for subtracting the total quantum threshold from the total dose level each time the total dose level exceeds the total quantum threshold, the summer summing the sequence of the integrated pulses by counting each time the total quantum threshold is exceeded by the total dose level for providing the dose output.
