AB  - A light source for testing and setting up radiological television systems has 
      been designed and built using green light emitting diodes and an optical 
      integrating sphere. It is shown to have an optical spectrum similar to the green 
      output phosphors used in x-ray image intensifiers (XRII's). It can be made 
      uniform in intensity across the output port and does not show the small scale 
      granularity characteristic of phosphors. It has a Lambertian angular distribution 
      which, by the addition of neutral density filters, can be made to mimic the 
      angular distribution at the output of an XRII. It can easily and accurately be 
      modulated or switched and a luminance comparable to that of an XRII output 
      phosphor can be achieved.
