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.
Gamma rays, x-rays, and some ultraviolet waves are ionizing, meaning these waves have such a high energy that they can knock electrons out of atoms. Exposure to these high-energy waves can alter atoms and molecules and cause damage to cells in organic matter.lectromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
