Japão vai lançar no mar água tratada de Fukushima
April 13, 2021 - O governo do Japão decidiu libertar água radioativa tratada da central nuclear de Fukushima para o oceano Pacífico – uma opção a que se opõem ferozmente os pescadores locais e os países vizinhos.
The accumulating water has been stored in tanks at the Fukushima Daiichi plant since 2011, when a massive earthquake and tsunami damaged its reactors and their cooling water became contaminated and began leaking. The plant’s storage capacity will be full late next year.
Prime Minister Yoshihide Suga said the ocean release was the most realistic option and that disposing the water is needed to complete the decades-long decommissioning of the Fukushima plant. He said the government would work to make sure the water is safe and to help local agriculture, fisheries and tourism.
The plant’s operator, Tokyo Electric Power Co., and government officials say tritium, which is not harmful in small amounts, cannot be removed from the water, but all other selected radionuclides can be reduced to releasable levels. Some scientists say the long-term impact on marine life from low-dose exposure to such large volumes of water is unknown.
