A radiation detection device comprising a plasma display panel (PDP) with a multiplicity of radiation detection pixels, each radiation detection pixel being defined by a hollow elongated Plasma-tube filled with an ionizable gas. Arrays of Plasma-tubes are positioned on a suitable base such as a substrate and used to inspect and detect radiation from a selected object. Each Plasma-tube may be of any suitable geometric configuration and may be used alone or in any combination with one or more Plasma-shells, such as a Plasma-disc, Plasma-dome, and/or Plasma-sphere. Luminescent material may be positioned near or on each Plasma-tube or Plasma-shell to provide or enhance light output. A flexible base substrate may be used to wrap a layer or blanket of radiation detection Plasma-tubes about the selected object. The substrate base may comprise an elongated rod that is used as a probe to detect radiation from an object. An object may be passed through a ring or a cylinder of Plasma-tubes.
