   For those of you who are “nuclear curious”, the attack on Iranian nuclear sites could have resulted in trace amounts of radioactive material getting kicked into the atmosphere. The Earth’s atmosphere is a river that flows across the globe, and other places will “see” those isotopes with sensitive enough instruments.

   Here is gamma radiation air monitoring open data, including data from #SNOLAB where I work. This data aids in nuclear non-proliferation.

     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.
