In the 1980s, scientists assessed the possible effects of nuclear warfare (many nuclear bombs exploding in different parts of the world) and proposed the theory that a nuclear winter could occur. In the nuclear-winter scenario, the explosion of many bombs would raise great clouds of dust and ...
(See How Nuclear Bombs Work for details.) The B61-11 can carry a nuclear charge with anywhere between a 1-kiloton (1,000 tons of TNT) and a 300-kiloton yield. For comparison, the bomb used on Hiroshima had a yield of approximately 15 kilotons. The shock wave from such an intense...
One reason many people oppose nuclear power is because they think nuclear plants are like enormous nuclear bombs, just waiting to explode and wipe out civilization. It's true that nuclear plants and nuclear bombs are both based on nuclear reactions in which atoms split apart, but that's genera...
And nuclear bombs are the best answer, Wie said. A Hypervelocity Asteroid Intercept Vehicle (HAIV) mission architecture, which blends a hypervelocity kinetic impactor with a subsurface nuclear explosion for optimal fragmentation and dispersion of hazardous near-Earth objects (NEOs), has been developed...
Uranium is not the only material used for making atomic bombs. Another material is the Pu-239 isotope of the man-made element plutonium. Plutonium is only found naturally in minute traces, so useable amounts must be produced from uranium. In a nuclear reactor, uranium's heavier U-238 isotop...
Two more Fat Man bombs were prepared to be deployed, with technicians working around the clock to get them ready for General LeMay. However, they were not prepared in time, sparing Sapporo, Japan from a second round of nuclear attacks on August 11 and 14. ...

Szilard was quite aware of the possibilities of nuclear fission: "These might lead to large-scale production of energy and radioactive elements, unfortunately also perhaps to atomic bombs," he wrote. The physicist played a leading role in producing the world's first atomic chain reaction at the...
scientists would use this legacy in a novel department of homeland security project—one that aims to hunt down the source of illegal nuclear material that could end up in bombs. ewing bequeathed the samples to his former postdoc, peter burns, then a professor at notre dame. and along ...
