Abstract: An embodiment of an active dosimeter system for detecting and communicating a radiation dose in real time is described that comprises a peripheral detector configured to be worn on an extremity or a head region of a user that includes a radiation sensor to detect ionizing radiation; a processor to determine a level of the ionizing radiation; and a wireless device to send a transmission comprising the detected level of the ionizing radiation; where the determination of the level of ionizing radiation and the transmission occur in real-time; and a receiver located in close proximity to the user that receives the transmission, and comprises an interface that informs the user of the detected level of the ionizing radiation.

Abstract: A system includes a pulse counter having a selectable pulse counter read-out rate, a pulse counter read-out (PCRO) storage register that stores a PCRO count, and a pulse-burst counter that has a pulse-burst counter read-out rate that is faster than all but the fastest selectable pulse counter read-out rate, a subtractor module in electronic communication with the pulse counter and the PCRO that subtracts the PCRO count from the pulse counter read-out count to output an uncorrected pulse count, a selection module in electronic communication with the pulse-burst counter that selects the pulse counter read-out rate in response to input from the pulse-burst counter, a multiplexer in electronic communication with the subtractor module and the selection module, the multiplexer selecting from among at least two dead-time correction transforms, the transform corresponding to the selected pulse counter read-out rate, and a control-and-readout module that outputs a dead-time corrected pulse rate.
