The Japanese regulation before and after

Here is the list of how the Japanese regulation on radioactive contamination changed before March 17th and after. The water contamination regulation by WHO is 1Bq/L and now Japan got I-131 for 300Bq/L. 300 times difference. And the Japanese academics are saying that the contaminations on vegetables can be washed away if they wash it with water. They don't know how to make a logic of washing something in a mad and make it still got dirty. Oh, I forgot to mention Cs-137. The Japanese regulation is 200Bq/L. Well, if you drink 1L of water, you might get up to 300Bq/L contamination of I-131 and Cs-137 for 200Bq/L. I don't know about the WHO's regulation is accountable for each element. Perhaps, if you add the possibilities of other nuclear elements including plutonium, the contamination would go up to around 1000Bq/L as the total amount of the health risk. Of course, the government officials can say that infants in Tokyo can drink the tap water once or twice.

How about cultivating potatoes? They need to sterilized to prevent the sprouting, and the contamination can make one process reduced for the packaging. And maybe the products can be sold to China as the country has the population problem.
