1. A system for detecting and locating sources of radiation emissions, comprising:

  • a hand-held probe including;

    a detector configured to generate a low-level electrical signal relating to gamma data emitted by a radiation source proximate the detector;

    a preamplifier configured to amplify the low-level electrical signal to a corresponding output electrical signal representing the gamma data;

    a controller configured to receive the output electrical signal, convert the output electrical signal to gamma data, and generate messages containing a predetermined number of bytes relating to the gamma data, and transmit the messages; and

    a probe wireless link configured to receive the messages from the controller, periodically transmit the messages containing gamma data relating to the low-level electrical signal; and

    an instrumentation console including;

    a housing,a console wireless link within the housing and configured to receive the messages periodically transmitted by the probe wireless link,a receiver electrically coupled to the console wireless link to convert the received messages to corresponding electrical indication signals,an indicator to convert the electrical indication signals to a perceivable indication relating to the amount of radiation detected, anda signal processor coupled to the receiver, the signal processor configured to execute a smoothing function for processing the gamma data from the messages, wherein the smoothing function includes synchronizing the gamma count data into five millisecond time interval bins and averaging incoming gamma count data values over ten bins to derive a smoothed gamma count, and the console wireless link and the probe wireless link both being configured as transmitter-receivers for bidirectional communication of data.
