Contamination of wild mushrooms serious in wide area / Facing radiation daily

As the data on radiation contamination of wild mushrooms have become more and more available, I list them here again.

The situation in Gunma prefecture becomes clearer. While no mushrooms with contamination levels above several tens of thousands were not found, many mushrooms are contaminated beyond the reference level.

Several cases in which the contamination level went beyond the reference level were found in Nagano and Saitama prefecture, in which few agricultural products were found contaminated beyond the reference level.

The biggest problem is that no data are available for Ibaraki, Chiba, Kanagawa and Tokyo prefectures.

There are still not many data for Miyagi-ken and Iwate-ken, either.

As the contamination of mushrooms can be an index of the contamination of forests, prefectural government should survey mushroom contamination levels as soon as possible.
