Radiation levels in the US

A Facebook warning from Andrew Fox in NYC

A warning for people in East Coast USA

9/10/2015, Queens NYC 

Ladies and gentlemen, brothers, sisters, comrades, and friends.

I would like to warn you that the rain coming down currently is contaminated with ionizing radiation.

What isotopes, and it's exact origin, I do not know with any certainty (although I can certainly make educated guesses).

The normal 'background radiation' in my neighborhood ranges from about 35-40CPM.

After walking from the 7 train to my apartment (~5 Minutes) in the rain, I tested my rain soaked shirt with my S.E. International, Inc. Inspector EXP Geiger Counter, I was extremely alarmed and saddened to see that my shirt registered a whopping 114.1CPM (after a standard ten minute timed measurement).

If you're in the rain, please cover up - and if you can avoid going out at all, even better
