You could always invest in a geiger counter an see how much radiation is around you. Personally I like a little radiation with my tea, the microwave provides just the right amount.
hello all, amoung many types of tea, I like to drink japanese green sencha tea, not so much a fan of the macha. But with the radiation problem in Japan, does anyone know if there are tea plantations around the damaged nuclear power site? I often buy this brand of japanese tea which says its grown somewhere near the base of Mt. Fuji which is south of Tokyo. Hopefully there are no tea plantations close by to that site, otherwise buying Japnese tea might become iffy.
