Document Summary

It is a part of our planet: background radiation it is natural radioactivity in the earth and by cosmic rays from outerspace. It can lead to mutation but does not usually cause harm to humans: manmade radiation cause by electronic products and is harmful to the human health. Manmade radiation is only 18% of all emitted radiations of which 4% is emitted from nuclear medicines (used to cure cancer) Natural radiation is 82% of all emitted of which 55% is emitted by radon. Radiation can be divided into 2 groups based on the amount of energy possessed by the radiation. Ionized high energy (cosmic, gamma rays, etc); it has short wavelengths. However, there is enough energy to break down chemical bonds and can harm our body: non ionized low energy (tv, microwaves, etc); it has long wavelengths. There is not enough energy to rearrange chemical arrangement. The affects it has on human health is still debated by scientists.
