Radiation is natural and found everywhere – it comes from outer space, the air we breathe, and the earth we tread. It's even in our bodies; naturally occurring radioactive elements in our bones irradiate us on average 5000 times per second.
Where is radiation commonly found?
Radiation can be found in soils, in our air and water, and in us. Because it occurs in our natural environment, we encounter it every day through the food we eat, the water we drink, and the air we breathe. It is also in building materials and items we commonly use.
What are the 3 main sources of radiation?
Natural background radiation comes from the following three sources:
- Cosmic Radiation.
- Terrestrial Radiation.
- Internal Radiation.
