Electromagnetic radiation

Electromagnetic rays, and gamma rays-is ionizing and therefore dangerous to physique tissues, dwelling cells, and DNA (deoxyribonucleic acid). The dangerous effects of ultraviolet mild to people and larger animals are mitigated by the truth that this type of radiation doesn't penetrate much additional than the skin.

The physique of a sunbather is struck by 1021 photons each second, and 1 % of these, or greater than a billion billion per second, are photons of ultraviolet radiation. Tanning and pure physique pigments assist to guard the skin to some extent, preventing the destruction of skin cells by ultraviolet light. Nonetheless, overexposure to the ultraviolet element of sunlight could cause pores and skin cancer, cataracts of the eyes, and harm to the physique's immune system. Luckily a layer of ozone (O3) within the stratosphere absorbs the most damaging ultraviolet rays, which have wavelengths of 2000 and 2900 angstroms (one angstrom [Å] = 10-10 metre), and attenuates those with wavelengths between 2900 and 3150 Å. Without this protective layer of ozone, life on Earth wouldn't be possible. The ozone layer is produced at an altitude of about 10 to 50 kilometres above the Earth's floor by a response between upward-diffusing molecular oxygen (O2) and downward-diffusing ionized atomic oxygen (O+). Many scientists consider that this life-protecting stratospheric ozone layer is being reduced by chlorine atoms in chlorofluorocarbon (or Freon) gases released into the ambiance by aerosol propellants, air-conditioner coolants, solvents used within the manufacture of electronic components, and other sources.

Ionized atomic oxygen, nitrogen, and nitric oxide are produced in the upper environment by absorption of solar ultraviolet radiation. This ionized region is the ionosphere, which affects radio communications and displays and absorbs radio waves of frequencies beneath forty MHz.
