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 scintillator (CsI (Tl), GSO ( Gd 2 SiO 5 (Ce)), LSO (Lu 2 (SiO 4) O (Ce)) and the photodiode using a phoswich sensor beta (beta) lines gamma consisting of (gamma) ray is described for the radiation monitoring devices and methods having the same time automatic measurements and nuclide determination function.; The present invention as described above is a radiation monitoring device plastic / inorganic scintillator (CsI (Tl), GSO ( Gd 2 SiO 5 (Ce)), LSO (Lu 2 (SiO 4) O (Ce)) phoswich detector for the radiation through the output signal of the monitoring device with a high sensitivity amplifier for amplifying the output signal of the phoswich detector, and for processing the amplified signal to the signal processor and the signal processor for and distinguish the beta and gamma radiation, comprising a control unit for controlling the nuclide determination It provides a radiation monitoring device.
