Claim 0:
1. A system for measuring a radiant exposure of electromagnetic radiation, comprising:
an accumulation detection module (AMD) configured to continuously monitor an exposure dose of the electromagnetic radiation, wherein the AMD comprises a detector configured to receive the electromagnetic radiation and generate a current responsively; an accumulation component connected in parallel to the detector and configured to receive the current generated by the detector and store electric charges corresponding to the generated current; and a discharge component connected in parallel to the detector and the accumulation component and configured to operably discharge the electric charges stored in the accumulation component;
a system-powered transmission component configured to transmit exposure dose information to a remote device; and
an adaptive circuit in electrical communication with the ADM and the system-powered transmission component and configured to periodically interrogate the ADM and adjust a frequency of interrogation of the AMD based on intensity of the electromagnetic radiation received by the detector, wherein the adaptive circuit comprises a trigger component configured to monitor a voltage across the accumulation component and generate a wake up signal when the voltage is equal to or greater than a predefined threshold voltage; at least one analog to digital converter (ADC) configured to translate the voltage into a digital input; and a processor configured to receive the wake up signal from the trigger component and in response:
interrogate the voltage of the AMD via said at least one ADC;
translate the digital output from said at least one ADC into the exposure dose information;
transmit the exposure dose information to a remote device via the system-powered transmission component; and
discharge the accumulation component via the discharge component.
