![]() ![]() That’s what happens in the Sun's core, where hydrogen atoms fuse to produce helium and energy. "Thermo" here simply means heat, because that method relies on achieving fusion via extremely high temperatures. There are several theoretical methods to attain fusion, but the one most exciting the modern scientific community is thermonuclear fusion. Eager scientists have pursued the harnessing of nuclear fusion's power-generating capacity for almost three-quarters of a century –the UK Atomic Energy Authority patented a fusion reactor in 1946 – but without reliable success. Each reaction releases energy, which can be harnessed for destruction – the bombs dropped on Japan in 1945 were fission, but fusion was behind the second-generation "H-bomb" and can generate vast amounts of power. In fission, the nucleus of an atom splits into two or more smaller nuclei in fusion, two or more nuclei combine. Japan’s worst nuclear disaster was in 2011, caused when an earthquake-triggered tsunami struck the Fukushima Daiichi plant.There are two types of nuclear power: fission and fusion. “There are many people in the Chernobyl area and in Fukushima that are concerned about having children after they have been exposed to radiation from these accidents,” she said, adding: “This paper should put their minds at rest – there is no risk of their exposure causing a problem for their children.” “The answer from this study is no – there is no evidence that radiation exposure to a parent results in defects at the level of DNA in the child,” Thomas, who was not involved with the study, said. Gerry Thomas, director of the Chernobyl Tissue Bank and Professor of Molecular Pathology at Imperial College London, told CNN that the study “uses modern technology to answer the question: ‘If I am exposed to higher than background levels of radiation and then go on to have children, will my children be affected by my exposure?’ Photographs capture an abandoned world inside the Chernobyl Exclusion Zone These changes randomly arise in a parent’s sperm and eggs although they are not observed in the parent’s genomes, they can be passed to their children. Researchers studied the genomes of the children for an increase in inherited genetic changes, known as de novo mutations. Parents in the study had experienced varying radiation doses. ![]() The team, led by Meredith Yeager, screened the genomes of the children, born between 19, and who were conceived after the accident – and did not find an increase in new genetic mutations in those studied, they said in a paper published in the journal Science.Įach parent was studied for exposure to ionizing radiation, either from their work in the clean-up or from environmental exposure. Hoping to better understand the effect of radiation exposure from the disaster, a team of scientists at the US National Cancer Institute (NCI) in Maryland studied 130 children born to 105 mother-father pairs, where at least one parent had been exposed to gonadal – reproductive gland – radiation, having worked as radiation cleanup workers or been evacuees from contaminated areas. Japan to start releasing treated Fukushima water into sea in 2 years Prime Minister Yoshihide Suga on Wednesday, April 7, 2021, told top fisheries association officials that his government believes the release to sea is the most realistic option and a final decision will be made "with days."(Kota Endo/Kyodo News via AP) Kota Endo/Kyodo News/AP The Japanese government has decided to get rid of the massive amounts of treated but still radioactive water stored in tanks at the wrecked Fukushima nuclear plant by releasing it into the Pacific ocean, a conclusion widely expected but delayed for years amid protests and safety concerns.
