  • GAMMA DETECTION SYSTEM INCORPORATING ELECTRONIC PROBE COLLIMATION
    Publication number: 20230092456
    Abstract: An instrument and software methodology to detect a radioactive source and incorporates the following: 1) two radiation detectors in a co-axial configuration, housed in a handheld probe, and 2) a gamma detection control unit executing software algorithms to limit the functional field of view to the front aspect of the probe, vary the depth and width of the field of view to provide collimation without the use of metallic shielding, and allowing the instrument to measure the distance to the radiation source.
    Type: Application
