Há 4 dias · Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive .
Há 1 dia · During fission, a fraction of the nuclear binding energy, which holds a nucleus together, is released as a large amount of electromagnetic and kinetic energy (much of the latter being quickly converted to thermal energy). Fission of a kilogram of plutonium-239 can produce an explosion equivalent to 21,000 tons of TNT (88,000 GJ).
Há 4 dias · Nuclear reactors are the major source of human-generated neutrinos. The majority of energy in a nuclear reactor is generated by fission (the four main fissile isotopes in nuclear reactors are 235 U, 238 U, 239 Pu and 241 Pu
Há 4 dias · The process of breaking apart atoms to create energy is called nuclear fission. It's different from nuclear fusion, which is when two smaller atoms are smashed together to create a bigger atom ...
Há 5 dias · But after the first Soviet nuclear bomb was tested in August 1949, several of the U.S.S.R.’s top physicists were redirected to harness the monstrous power of nuclear fission for energy ...
Há 1 dia · nuclear power, electricity generated by power plants that derive their heat from fission in a nuclear reactor. Except for the reactor, which plays the role of a boiler in a fossil-fuel power plant, a nuclear power plant is similar to a large coal-fired power plant, with pumps, valves, steam generators, turbines, electric generators, condensers ...
Há 6 dias · And when? (warning: layperson ignorance to follow) I’ve been reading up on it a bit and I kind of get the gist of the progression leading up to it (in a layman kind of way) but who first thought, ‘I could use this to blow stuff up’. Wiki says, In a 1924 article, Winston Churchill speculated about the possible military implications: "Might not a bomb no bigger than an orange be found to ...
