Claims

[Scope of utility model registration request]

Radiation detection by housing a composite ionization chamber in which a large number of composite ionization chambers are arranged alternately between a pair of insulating substrates facing each other with a high-voltage electrode plate and a signal electrode plate spatially isolated and placed in a container filled with a gas having a large radiation absorption coefficient. In the device, a plurality of protrusions are formed on two sides of the high voltage and signal electrode plate on the side supported by the insulating substrate, and a plurality of small protrusions are formed on the pair of insulating substrates into which the protrusions of the electrode plate are fitted. An ionization chamber type radiation detector characterized by having holes.
