Scientists will lower radiation level on Fukushima by means of corn
Scientists of Japanese university Ivate have found a way to clear soil from radioactive substances by means of the activated coal made of corncobs, informs ITAR - TASS referring to Japanese mass-media.
Japanese researchers have established that porous coal which is formed at burning of corncobs, effectively absorbs radioactive particles, heavy metals and pesticides. According to the experiments spent at university Ivate, the caesium maintenance in the cabbage which has been grown up on deactivated “ corn coal “ to soil, it was possible to lower for 60 percent. For weeding from radiation its top layer have preliminary mixed with coal.
According to the researchers, the given technology is useful at deactivation of extensive territories which have undergone to radioactive pollution after failure on the atomic power station “ Fukushima - 1 “ in the spring of 2011. In radius of 60 kilometres around “ Fukushima - 1 “ the earth has appeared unsuitable for agriculture at least for 600 years, inform local mass-media. Farmers from prefecture Fukushima try to grow up the vegetables which are not sheet, to reduce possible influence on them of radiation. However buyers to be afraid to get such production.
After accident in prefecture Fukushima consumption and sale of all sheet vegetables (spinach, komatsuna - bitter Japanese spinach, - cabbage and parsley), and also krestotsvetnyh (the broccoli and a cauliflower) have been suspended. Blow on agriculture was followed by blow on a demography. As reports “ Kjodo “ and without that the growing old population of coastal prefectures Ivate, Mijagi and Fukushima of region Tohoku at the expense of migration for a year was reduced to 2,2 percent, that is on 55,6 thousand persons.
