Directional gamma detector

A directional gamma detector comprising a detection probe and a handgrip, wherein said detection probe comprises:

• a supporting rod;
• a detection head coupled or integrated with a first end of said supporting rod and comprising a plurality of detection elements which are separate from each other for simultaneously detecting gamma radiation directed along respective directions different to each other, each detection element comprising at least one scintillation crystal and a corresponding first electronic conversion circuitry for receiving an optical signal from the crystal and converting the optical signal from the crystal into an electrical signal, each of said detection elements being associated with a respective collimator made of a material with a high atomic number and suitable to screen the gamma radiation striking said detection element with a predetermined external angle and a solid angle;
• and wherein said handgrip can be gripped manually by an operator and is equipped internally with a second electronic circuitry for converting and/or processing the signals;
• wherein said measuring probe is reversibly connectable to the handgrip by means of a mechanical connector equipped with electrical contacts for transferring the signals from said first electronic conversion circuitry to said second electronic circuitry for converting and/or processing the signals;
• wherein said plurality of detection elements comprises a central detection element, aligned with a main collimation axis, and at least one pair of lateral detection elements aligned along respective collimation directions transversal to said main axis of collimation.
