■ Contamination situation of mushrooms after Fukushima nuclear accident
Autumn of taste, season of mushroom has come this year. The parents of such staff N also had the pleasure of the wild vegetables hunting and the mushroom hunting which went out on the trip for the fun of old age. However, after the nuclear accident, N became involved in the measurement, and after knowing cesium of wild mushrooms, there was no pleasure. It is sad.
In this chapter's map collection "Chapter 2 Food", we also cover wild mushrooms.
Mushrooms are originally easy to take up cesium, and in particular, wild mushrooms that can not control the culture medium are still found in many prefectures that exceed standard levels.
It is information that many people should know by all means in order to prevent "unintentional eating and internal exposure". ■ Contamination situation of mushrooms after the Fukushima nuclear accident Wild mushroom contains at least 10 times more radioactive cesium than cultivated mushrooms distributed in the market. Contamination is higher in "mycorrhizal fungi" in symbiosis with the roots of trees than in "harmful fungi," which grow by rotten dead trees and dead leaves. It is thought that the size of the concentration range and the yearly fluctuation range found in wild mushrooms is the difference between the number of examinations and the area. While high-value mushrooms like Matsutake are widely collected in a large number of areas and tested, mushrooms with high concentration contamination are limited in data collection because they are not collected.
In addition, since there are regional differences in the collected wild mushroom species, it can not be said that it reflects the current state of wild mushrooms, so further data accumulation is desired. The figure extracts the inspection data of 30 kinds of wild and cultivated mushrooms from 2012 to 1717 from "radioactive substance inspection data in food" of the Ministry of Health, Labor and Welfare, and distribution and secular change of radiocesium concentration included in each mushroom species What I examined. For "wild mushroom", we selected mushroom species with a relatively large number of tests, and classified them into "mycorrhizal fungi" and "phthus". For "cultivated mushrooms", mushroom species with a large amount of production are selected. Those that can not distinguish between cultivation and nature are clearly stated. Note: Of the three graphs, note that in the upper figure the upper limit of the vertical axis is 800 Bq / kg, and in the lower figure the scale is different from 50 Bq / kg. This book also contains a wealth of commentary on food data using graphs and tables. ★ Reservation is here! Crowdfunding is underway until September 28!
