Radiation effects on electronic equipment

 · Ionizing radiation breaks down the materials within the electrical equipment. For example, when wiring is exposed to gamma rays, no change is noticed until the wiring is flexed or bent. The wire''s insulation becomes brittle and will break and may cause shorts in the equipment. The effect on diodes and computer chips is a bit more complex.
