Well, that is a question I ask myself daily. Today I decided to find out.The most common radioactive elements in food are K-40 (Potassium), R-226 (Radium), and U-238 (Uranium). The foods with the highest radioactive element content are:*
[Food, K-40(Bq/Kg), R-226(Bq/Kg)]
1) Brazil nuts; 207, 40 to 360.
2) Lima beans (raw); 170, 0.
3) Bananas; 130, 0.
4) White potatoes; 126, 0.
5) Carrots; 126, 0.
6) Red meat; 111, 0.
7) Beer; 14.4, 0.
Apparently, eating 600 bananas is equivalent to having a chest x-ray (see article in Discover magazine entitled 'Everything Emits Radiation'). I always knew bananas were, in the words of Michael Jackson, D-a-n-g-e-r-o-u-s.
What is the most radioactive lunch you have eaten?
Stay wary, and free of ionizing radiation lunchers!
