Curious about radiation doses, and what is normal and what is not? Learn more from the #Sievert wikipedia page:
https://en.wikipedia.org/wiki/Sievert
While 2 mSv is the typical ambient background radiation dose you get merely from living on this planet, the occupational dose limit (where health risks begin to increase) is 50 mSv per year.
Trace amounts of radioisotopes will generate much less, but potentially more than 60 nSv/h. Will be interesting to watch in coming days.
