Radiation oncology is the medical specialty concerned with prescribing radiation, and is distinct from radiology, the use of radiation in medical imaging and diagnosis. Radiation may be prescribed by a radiation oncologist with intent to cure (curative) or for adjuvant therapy.
Earth's atmosphere also play a vital role in regulating the temperature by providing a blanket of gases that not only protects us from excessive heat and harmful radiation from the sun, but also traps heat rising from the Earth's interior, keeping us warm. The average temperature on Earth is about 61 degrees F (16 C).But temperatures vary greatly around the world depending on the time of year, ocean and wind currents and weather conditions. Summers tend to be warmer and winters colder. Also, temperatures tend to be higher near the equator and lower near the poles.arth's atmosphere also play a vital role in regulating the temperature by providing a blanket of gases that not only protects us from excessive heat and harmful radiation from the sun, but also traps heat rising from the Earth's interior, keeping us warm.

Earth would be too cold for life if it had no atmosphere. The atmosphere holds enough of the sun's heat to make life possible here. Temperatures on earth range from a high of perhaps 130 degrees Fahrenheit to about -90 Fahrenheit.There are places on earth in which it is challenging for us to stay alive. There are living things in most earth environments, however.arth would be too cold for life if it had no atmosphere. The atmosphere holds enough of the sun's heat to make life possible here.
