bananas are radioactive, they have high levels of potassium, one isotope of K is radioactive. it's not going to kill you or anything. but i had to do a radiation safety course a few years back and we had to know how to calc exposure, decay time etc and eating lots of bananas was a factor in working out an individuals radiation exposure. http://chemistry.about.com/b/2008/08/11/bananas-are-radioactive.htm
That's fucking amazing. I need people more people in my life who tell me things like that. Elope with me?
