Abstract
A simplified ion chamber for determining radiation from an X-ray source with the chamber having a single emitter electrode and a collector electrode of substantially the same size. A spacer element for positioning between the emitter and the collector electrodes is composed of a molded cellular plastic sheet with open areas molded in the sheet for alignment with ion collecting areas of the collector electrode and the open areas being formed with tapered walls. The spacer element also has pathways formed by higher density areas corresponding to conductive pathways of the collector electrode.
