Description
I mostly use this exercise as a "see, most of your radiation does is NOT from nuclear plants."  I have used this in both General Chemistry and Inorganic Chemistry when doing a nuclear chemistry or energy production unit.

Students love this exercise. They are quite surpised at the difference of living near a coal vs. a nuclear plant.

Of course, some of your radiation DOES come from nuclear power plants. This has hit home recently after the earthquake and tsunami in Japan that severely affected the Fukushima power plants.   This graph does a good job of showing the relative doses from a variety of sources. So does this one.

The original author states "I waive all copyright to this chart and place it in the public domain, so you are free to reuse it anywhere with no permission necessary. (However, keep in mind that I am not a radiation expert, and this chart is intended for general public informational use only.)"

In the graphic, it is a bit more explicit:  "If you're basing radiation safety procedures on an internet PNG image and things go wrong, you have no one to blame but yourself."

However, it is a good graphic that shows natural and unnatural sources of radiation.
