Few days ago it was announced that 6 cows which were radioactive were sent out to restaurants and supermarkets (4 times more than average). Now they think that it was 400+ cows. The reason why these cows were more radioactive than usual is because the farmers fed them grass that had been contaminated with radiation. Workers from Fukushima who work to supply the meat are saying on TV that they are trying their best to check for meat with high radiation, but of course this is hard since they need the equipment which is very expensive. BBQ restaurant owners were crying as they felt guilty for supplying meat to their customers which was contaminated (they were also angry because they did not know that it was radioactive meat until now).
We will be careful when eating domestic meat now, though in Japan it is typical to avoid American meat (due to the mad cow disease) and domestic beef is considered to be delicious and high quality.
As I hear news about radiation, I began to worry about the radiation in the air.
The amount of radiation in the air seems to be stabalizing (not Fukushima area but the other areas). I checked this website : http://atmc.jp/. It seems like the average in Kanagawa prefecture is usually between 0.035μSv/h to 0.069μSv/h. In Tokyo, the numbers are similar. Now, you can see the radiation levels around the world if we go here. When the Fukushima Daiichi Nuclear Power Plant was having trouble back in March, Tokyo/Kanagawa recorded radiation levels that were as high as New York's normal radiation level (like 1.0 to 2.0) and people were panicking. Should I be worried about natural US radiation levels in the air?
