WebFeb 3, 2013 · Gamex CR 2.0 is the second, considerably modified version of the program. The most important novelty is a fundamental change in exposure time calculation methodology. It is no longer based on the ISO/CEN speed of IP plates as this approach created some problems for program users. WebTwo of the more common industrial gamma-ray sources for industrial radiography are iridium-192 and cobalt-60. These isotopes emit radiation in a few discreet wavelengths. Cobalt-60 will emit a 1.33 and a 1.17 MeV gamma ray, and iridium-192 will emit 0.31, 0.47, and 0.60 MeV gamma rays.
