Good Morning!!!

I know people that would do this...

Nice...

In the big scheme of things, the answer is no. He uses Sieverts as the scale, but I'm am use to REM.  In reality, the average person is exposed to this radiation every day.  There is even a Unit of Measure called Banana Equivalent Dose. 

The federal limit is no more than 3 REM/quarter not to exceed 5 REM/ year for occupational workers.  At this rate, it is expected that the cancer rate might increase by 0.01%.  As a non-occupational worker, I'm allowed 100 mREM/year per NAVSEA.

And the .gov has a lot of experience with radiation exposure, as they have been studying the survivors of Hiroshima and Nagasaki.

And because a lot of people don't know the difference between Radiation and Contamination, a simple analogy:

Contamination is the dog crap in the yard, radiation is the smell.

Bottom Line:

We are exposed to some radiation every day, and we are not harm/affected by it in any way.

Hope you have a spare or it's going to be a long walk back to town...
