Сцинтилляционный детектор на основе кристаллов йодистого натрия, активированных таллием (NaI(Tl))

Описание товара

An energy-sensitive detector for identifying γ-ray and X-ray fluorescent radiation with high probability. It can record energy spectra, which can be calibrated, and measure the relative intensity of the radiation. Incoming radiation causes a thallium-doped sodium iodide crystal to emit brief pulses of light, which are then converted into electrical pulses in proportion to the energy of the radiation by means of a photomultiplier affixed to the apparatus. The crystal is protected against light penetrating from outside by a thin aluminium cover. The photomultiplier is protected from interference by external magnetic fields by means of mu-metal shielding.
