Calculate Your Dose

Despite nuclear engineers discussing that nuclear power plants result in very small doses to the public, it's better to show than to tell.

First: Calculate dose due to where I live:
1.     Cosmic radiation is unavoidable
2.     I live less than 100 ft above sea level
3.     Florida is on the Gulf Coast
4.     I live in a concrete building
Second: Dose to what I eat, drink, and breathe
1.     Radiation in your body (240 mrem)*

2.     From food and water (40 mrem)

3.     From radon in the air (200 mrem)

Third: Dose to other sources
  1. Weapons test fallout (1 mrem)**
  2. Miles of travel by jet plane annually: I’m in a long distance relationship and I have a lot of family abroad so I probably travel around 15,000-20,000 miles.
  3. I also have to have my luggage inspected at airports (using typical x-ray machine) (0.002 mrem)
  4. I watch Watch TV (1 mrem) **
  5.  I use a video display terminal (1 mrem) **
  6.  I have a smoke detector (0.008 mrem)
  7. There is a coal-fired electrical utility plant within 50 miles of my apartment in Gainesville (0.03 mrem)
Before I tell you my annual dose, let me point out that you get 3 times as much radiation per year from living next to a coal plant than a nuclear plant. Even then, a coal plant will give you a dose of 0.03 mrem. The average american is expected to get about 350 mrem a year and 0.03 mrem is insignificant to your total dose. 

My annual dose is 320.04 mrem. Consider that I am allowed by the Nuclear Regulatory Commission (NRC) to get up to 5,000 mrem more per year without worrying about increasing my cancer risk. Even then, the company I will be working for next year only allows me to get 1,000 mrem more. Calculate your own dose and let me know how it goes!

*This is the annual dose average.
**The value is actually less than 1.

  1. This post was very practical and has helped me in my life. I always tell people about how their smoke detectors use nuclear technology but I never considered their contribution to our overall annual doses! Nothing to be concerned about, just fascinating.

  2. Nice post, it's good to both show people just how many things in their life give radiation that they don't expect, but also that that radiation has been determined to not be a concern to public health.
