Describe the sources of ionizing and non-ionizing radiations and their effects on the biotic components of the atmosphere.. (250 Words)

Features	Ionizing radiations	Non-ionizing radiations
Definition	Ionizing radiation consists of highly-energetic particles or waves that can detach (ionize) at least one electron from an atom or molecule.	Non-ionizing radiation (or, esp. in British English, non-ionising radiation) refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules — that is, to completely remove an electron from an atom or molecule.
Examples and sources	Ionizing radiation is abundant in space. A rain of particles, along with the electromagnetic radiation, arrives at the top of the Earth's atmosphere from space. Most of it is filtered by our atmosphere.	Near ultraviolet, visible light, infrared, microwave, radio waves, low frequency RF and static fields are all examples of non-ionizing radiation.
Health effects	Ionizing radiation has many practical uses in medicine, research, construction, and other areas, but presents a health hazard if used improperly. If enough ionizations occur in a biological system, they can be destructive, by such means as causing DNA damage in individual cells. Extensive doses of ionizing radiation have also been shown to have a possible mutating effect on the victim's gametes.	Non-ionizing radiation is not mutagenic. The use of this type of radiation in medical fields and everyday life poses fewer health risks than ionizing radiation in forms such as X-rays. Strong non-ionizing radiation has a heating effect. They primarily affect eyes and skin which are the most exposed parts.
