Rassure-moi, tu ne parles pas des rejets maximums autorisés sur toute une année pour ta comparaison d'impact?
J'ai peut-être juste mal compris, si c'est le cas mea culpa. Sinon faut juste comparer ce qui est comparable, pour ne pas induire en erreur. (Je ne dis pas que "c'est grave" ou que "ce n'est pas grave") (source de la Pièce Jointe ici) |

source : Japan news http://search.japantimes.co.jp/cgi-b...0110405x1.html The unstoppable radioactive discharge into the Pacific has prompted experts to sound the alarm, as cesium, which has a much longer half-life than iodine, is expected to concentrate in the upper food chain. According to Tepco, some 300,000 becquerels per sq. centimeter of radioactive iodine-131 was detected Saturday, while the amount of cesium-134 was 2 million times the maximum amount permitted and cesium-137 was 1.3 million times the amount allowable.The amount of iodine-131 dropped to 79,000 becquerels per sq. centimeter Sunday but shot up again Monday to 200,000 becquerels, 5 million times the permissible amount. The level of radioactive iodine in the polluted water inside reactor 2's cracked storage pit had an even higher concentration. A water sample Saturday had 5.2 million becquerels of iodine per sq. centimeter, or 130 million times the maximum amount allowable, and water leaking from the crack had a reading of 5.4 million becquerels, Tepco said. "It is a considerably high amount," said Hidehiko Nishiyama, spokesman for the Nuclear and Industrial Safety Agency. Masayoshi Yamamoto, a professor of radiology at Kanazawa University, said the high level of cesium is the more worrisome find. "By the time radioactive iodine is taken in by plankton, which is eaten by smaller fish and then by bigger fish, it will be diluted by the sea and the amount will decrease because of its eight-day half-life," Yamamoto said. "But cesium is a bigger problem." The half-life of cesium-137 is 30 years, while that for cesium-134 is two years. The longer half-life means it will probably concentrate in the upper food chain. Yamamoto said such radioactive materials are likely to be detected in fish and other marine products in Japan and other nations in the short and long run, posing a serious threat to the seafood industry in other nations as well. "All of Japan's sea products will probably be labeled unsafe and other nations will blame Japan if radiation is detected in their marine products," Yamamoto said. Tepco on Monday began the release into the sea of 11,500 tons of low-level radioactive water to make room to store high-level radiation-polluted water in the No. 2 turbine building. The discharge continued Tuesday. sympa pour un truc qui fuit et se deverse dans l ocean bon appetit |

According to NHK, "a radiation monitor at the troubled Fukushima Daiichi nuclear power plant says workers there are exposed to immeasurable levels of radiation." Unfortunately for the workers present, the monitor is not being metaphoric: "The monitor told NHK that no one can enter the plant's No. 1 through 3 reactor buildings because radiation levels are so high that monitoring devices have been rendered useless. He said even levels outside the buildings exceed 100 millisieverts in some places." |

des travailleurs sont en train -littéralement- de donner leur vie pour limiter les dégâts.
pendant ce temps, que donnent les vrais responsables de ce fiasco? |
