because its radiation and it spreads far and and it is very poisinous and you could die of it

The average worldwide exposure of people to environmental background radiation is about 2.4 mSv (milliSievert) per year. The referenced source does not break that down by country.Ref: "Report of the United Nations Scientific Committee on the Effects of Atomic Radiation to the General Assembly", http://www.unscear.org/docs/reports/gareport.pdf
Nuclear transmission is that measurement of amount of radiation found inside of a shield versus the outside. The transmission is the amount of radiation that is received by passing through the protective shield.
Light, heat, and a very small amount of electromagnetic field.
radiation balance
The north pole receives more solar radiation during the summer than the equator does, but during winter, it receives no solar radiation. This means that as latitude increases, the amount of solar radiation increases in the summer and decreases in the winter.

How: Earth receives the Sun's radiation as sunlight (and a smaller amount of invisible light, such as infrared and ultraviolet radiation). This is a huge amount of power received by Earth.
Granite does not give off radiation, though it may contain trace amounts of material which does. Any amount of radiation it releases should be insignificant (i.e. background radiation).
The ozone layer has the greatest effect on the amount of ultraviolet radiation received at the earth's surface from the Sun. Cloud formation and atmospheric thickness, in combination with solar angle, have the greatest effect on the amount of visible and infrared radiation received at the earth's surface from the sun
what location on earth receives roughly the same amount of solar radiation year round
Short wavelength radiation such as Ultraviolet fall to absorption spectrum band of Ozone. Ozone absorb UV and re-emitted the radiation in the range of infrared or thermal range radiation.
Today, the background radiation in Hiroshima and Nagasaki is the same as the average amount of natural radiation present anywhere on Earth. It is not enough to affect human health. http://www.pcf.city.hiroshima.jp/kids/KPSH_E/question_box/question12.html
The amount of oxygen increased greatly
