Radiation pollutants

When we are talking about radiation then we speak about ionizing radiation; it carries enough energy to free electrons from atoms or molecules. The most important consequence of this displaced electron on human tissue is the potential damage it can inflict on DNA, which may occur directly or indirectly. Direct damage occurs when the displaced electron hits and breaks a DNA strand. Indirect damage occurs when the electron reacts with a water molecule, creating a powerful hydroxyl radical which then damages the cell’s DNA. Gamma rays (including alpha and beta particles), X-rays and the higher ultraviolet part of the electromagnetic spectrum are ionizing.

To make it more clear:

The higher spectrum of any electromagnetic field is a radiation pollutant and that means also the ultra violet spectrum of the sun light.

It has to be considered as a radiation pollutant, it is ionizing and it is dangerous!
