What are the sources of radiation based on their wave frequency, and how do they impact the human body?

As the wave frequency rises, so does the energy with which it affects the human body. Following the visible spectrum, the waves are classed as ionizing radiation. Ionizing radiation harms the human body at the subcellular, cellular, and tissue levels, as well as the organism as a whole. The longer the radiation and the greater the wave frequency, the more damaging the effects on the human body.
