Radiation source localization systems and related techniques are provided to improve the operation of handheld or unmanned mobile sensor or survey platforms. A radiation source localization system includes a logic device configured to communicate with a communications module and a directional radiation detector, where the communications module is configured to establish a wireless communication link with a base station associated with the directional radiation detector and/or a mobile sensor platform, and the directional radiation detector includes a sensor assembly configured to provide directional radiation sensor data as the directional radiation detector is maneuvered within a survey area.

Radiation source localization systems and methods

Various techniques are provided to detect the direction and location of one or more radiation sources. In one example, a system includes a plurality of radiation detectors configured to receive radiation from a radiation source. A first one of the radiation detectors is positioned to at least partially occlude a second one of the radiation detectors to attenuate the radiation received by the second radiation detector. The system also includes a processor configured to receive detection information provided by the first and second radiation detectors in response to the radiation, and determine a direction of the radiation source using the detection information. A modular system including gamma radiation detectors and neutron radiation detectors and related methods are also provided. In some cases, radiation source type may be determined in addition to or separate from radiation source direction.
