Disclosed is a radiation detector provided at both ends with radiation source position detecting means each including three to five electrode plates in which a bias electrode plate centrally disposed has cover layers on both surfaces, and signal electrode plates disposed on both sides of the bias electrode plate each have a cover layer on only one surface farther from the bias electrode plate. Material of the cover layer has a smaller secondary electron emissive power than that of the material of the electrode plates with respect to incident radiation.

A multichannel radiation detector comprising a body, radiation source position detecting means disposed at each end of the body for detecting the position of a radiation source, each of said radiation source position detecting means having at least one positional deviation sensing cell including a grouping of three to five electrode plates, said grouping having alternately disposed bias and signal electrode plates, wherein the central electrode plate of said grouping is a bias electrode plate having a cover layer on both surfaces while predetermined ones of the remaining electrode plates of said grouping have a cover layer on only one surface thereof, said cover layer of said central electrode plate and said predetermined ones of the remaining electrode plates being a material having a smaller secondary electron emissive power for the incident radiation than that of the material of said respective electrode plates, and wherein said electrode plates of said groupings are disposed so that respective cover layers face the exposed surface of the adjacent electrode plate.
