Charged particle detector and detecting apparatus utilizing the same

A detecting apparatus, comprising:

• a charged particle detector, comprising:
• a metallic frame having one or more holes formed therein;
• a light transmitting member fixed in each of the holes of the metallic frame;
• an inorganic scintillation element mounted on a first side the light transmitting member;
• said inorganic scintillation element has a thickness substantially equal to a range for energy of alpha rays to be detected;
• a photodetector mounted on a second side of the light transmitting member opposite said first side;
• a light shield film on a surface of the inorganic scintillation element,
• a neutron generator for generating charged particles and neutrons;
• and
• a gamma ray detector for detecting gamma rays emitted when the neutrons are radiated onto an inspection object, wherein
• according to a result of detection by the charged particle detector and a result of detection by the gamma ray detector, elements of the inspection object are identified and thereby detecting an explosive.
