Claims

[Scope of utility model registration request]

A sealed container, a plurality of elongated insulating plates arranged substantially parallel to each other in the sealed container, and the side number of each of these insulating plates? The formed insulating plate has signal electrodes arranged in the longitudinal direction, and high voltage applying electrodes formed on the other surfaces of the insulating plates, and these signal electrodes and high voltage applying electrodes form an ionized space. They are spaced apart and facing each other, and the radiation is incident from a substantially straight direction onto a two-dimensional plane defined by the direction in which the signal electrodes are arranged on the insulating substrate and the direction in which the signal electrodes are arranged on the insulating substrate. A radiation detector characterized by:
