A while back read that brazilian nuts are radioactive.. are they safe to eat/touch? should you wash your hands after touching them?

Brazil Nuts: Just about all the food we consume has tiny amounts of radioactivity. Some foods contain more than others. While a small amount of it is due to nuclear fallout and industrial pollution, most of it is natural. Brazil nuts have the most naturally occurring radioactivity of any foods.This doesn’t mean we should avoid them. The amount is way too small to have any permanent effects.

Safe to eat, touch: Natural radiation occurs everywhere. Lots of foods have it. Brazil nuts and shellfish appear to have the most but it is still a small amount, when compared to other natural sources. Acc, to NRC, natural sources of radiation account for 50% of a person's lifetime radiation exposure. Nobody knows the effect of small amounts. Brazil nuts have 872 calories in a cup, too much makes you fat,- riskier!
