Radiation detection system with a foil means for emitting radiant energy
 A radiation detector capable of withstanding illumination by relatively concentrated electromagnetic energy is disclosed herein. The radiation detection system 10 of the present invention includes a sensor assembly 14 for generating radiant energy upon illumination by incident electromagnetic radiation R. The sensor assembly 14 will preferably include a sheet of metallic foil 24 for emitting the radiant energy into a sensor chamber defined by the assembly 14. The inventive radiation detection system 10 further includes an optical fiber cable 18 in communication with the sensor chamber. Radiant energy from within the sensor chamber is guided by the fiber cable 18 to a shielded detector arrangement 20 disposed to provide a detection signal indicative of the intensity of the incident electromagnetic radiation R.
