The eye detects visible light, the nerves detect infrared or heat and the skin is sensitive to ultraviolet ( tanning and sunburn ) and the lens of the eye develops cataracts in response to UV also. a human body can detect ionizing electromagnetic radiation, if he can see what his geiger counter is reading.
Risk: Gamma rays and X-rays. As you know, radiation can damage the body. Just a single high-energy photon of gamma rays can cause significant damage to a living cell. Once again, though, the Earthâs atmosphere is there to protect us. The molecules in the atmosphere absorb the high-energy photons preventing any from reaching us on the ground. In fact, X-ray and gamma ray observatories need to be built in space because thereâs no way we can see them from the ground.
