A Miniature Versatile Dosimeter

A miniature glass dosimetry system, is described that, when employed with a gold shield of suitable wall thickness and ``softer energy'' portals, is energy independent over a specified photon energy spectrum. A brief review of the characteristics that this dosimeter must meet before its use as a clinical in vivo doosimeter is included. Various physical characteristics relating to range, integration of daily dose, and orientation with respect to the source of radiation, etc., are also considered. Its clinical applications are reviewed as well as its use with radium and other discrete sources as implants. A brief review is made of its possible use in the detection of gamma radiation in the presence of neutrons. The applications of this dosimeter, as the authors indicate, are not limited to any specific field; rather, its use is determined if one wants the daily and/or total dosage of radiation delivered to a specific point. A separate electronic reader is required to read the dosimeter.
