Is Bottled Taiwanese bottled Japanese Green Tea safe from radiation?

You know, I feel like a bit of an idiot for drinking any tea that says Japanese on it at the moment, even if I love the country of Japan and wish them only the best. I just don't want to deal with cancer is all, so no hard feelings. Anyway, I purchased this Green Tea which is bottled and imported from Taiwan, it says "Japanese Green Tea" now I just wonder, are the leaves produced in Japan or Taiwan? Obviously they are capable of oxidizing tea with steam in Taiwan in the Japanese fashion, do you think they are selling me nuclear tea? Will I begin to glow and truly grow a 3rd eye? How enlightened I will be then huh? I just wonder, should I be worried since I just drank about 4 liters of this in the last 2 weeks?
