Alpha, beta, gamma and X-ray radiation can be detected using silicon PIN photodiodes either indirectly via the measurement of the luminescence radiation of a scintillation crystal or directly via the absorption in the crystal lattice. The Series X from First Sensor has optimized silicon PIN photodiodes, which form broad, fully depleted space-charge regions even at low reverse voltages so as to ensure maximum absorption of radiation. For high-energy radiation, First Sensor offers detectors with a CsI:TI scintillation crystal.
