The Particle Physics Of You

You are made up of a lot, and I mean, A LOT, of elementary particles. This Symmetry article reveals a bit more of what particles formed you, and their basic properties and history.

But what I'm sure many of you do not realize is that you are also the source of radioactivity.

Your body is a small-scale mine of radioactive particles. You receive an annual 40-millirem dose from the natural radioactivity originating inside of you. That’s the same amount of radiation you’d be exposed to from having four chest X-rays. Your radiation dose level can go up by one or two millirem for every eight hours you spend sleeping next to your similarly radioactive loved one. 

So next time you run into someone who is rabid anti-radiation and claims that no amount of radiation is safe, tell him/her to ban him/herself.
