Planar HPGe detector for gamma and X-ray spectroscopy from 3 keV, with sensitive areas from 20 mm² to 1000 mm².
The GPD converts gamma and X-ray quantum energy to signals proportional to their energy level. It is intended for use as the gamma and X-ray detection component of radiological monitoring equipment for environmental objects in nuclear energy, industrial production, agriculture and medicine.
