Apparatus and method for detecting a radiation having function of automatic measurement simultaneously Beta and gamma ray by using Plastic/inorganic scintillator with photodiode phoswich sensor

摘要

Plastic / inorganic scintillators (CsI (Tl), GSO (Gd ₂ SiO ₅ (Ce)), LSO (Lu ₂ (SiO ₄ ) O (Ce)) and Force position consisting of a photodiode (phoswich) and a beta (beta) gamma lines (gamma) ray using a sensor at the same time automatic measurements discloses a radiation monitoring device and method having a function to determine the nuclides. ; is the invention as and the plastic / inorganic scintillators for radiation monitoring device (CsI (Tl), GSO (Gd ₂ SiO ₅ (Ce)), LSO (Lu ₂ (SiO ₄ ) O (Ce)), a position detection and force, and a high-sensitivity amplifier circuit for amplifying the output signal of the force detector position for the radiation monitoring device, to process the amplified signal to the signal processor and distinguish between beta and gamma radiation from the output signals of the signal processor, and provides a radiation monitoring device comprising a controller for controlling the nuclide determination.
