Unfortunately, CEHPAC fails to realize that all radiation is not created equal. That is because of the physical fact that different kinds of radiation contain different amounts of energy. (The relative strength, in decreasing order, is nuclear radiation, X-rays, UV light, visible light, infrared light (heat), microwaves and radio waves.) The energy of nuclear radiation, X-rays and UV light is high enough to damage our bodies and cause cancer. But the other forms of radiation are energetically weak by comparison. They cannot cause cancer.
