Radioactive waste is a type of hazardous waste that contains radioactive material.It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. [1]
For two thermonuclear bombs for which the general size and primary characteristics are well understood, the Ivy Mike test bomb and the modern W-80 cruise missile warhead variant of the W-61 design, the radiation pressure was calculated to be 73 × 10 ^ 6 bar (7.3 TPa) for the Ivy Mike design and 1,400 × 10 ^ 6 bar (140 TPa) for the W-80.

Proposed pictogram warning of the dangers of buried nuclear waste for the Waste Isolation Pilot Plant. Long-term nuclear waste warning messages are communication attempts intended to deter human intrusion at nuclear waste repositories in the far future, within or above the order of magnitude of 10,000 years. Nuclear semiotics is an ...
In reactors, the radioactive products are the nuclear waste in spent fuel. In bombs, they become radioactive fallout, both local and global. [9] Meanwhile, inside the exploding bomb, the free neutrons released by fission carry away about 3% of the initial fission energy.
The federal government and companies responsible for nuclear bomb production and atomic waste storage sites in the St. Louis area in the mid-20th century were aware of health risks, spills ...
Nuclear fallout is the distribution of radioactive contamination by the 520 atmospheric nuclear explosions that took place from the 1950s to the 1980s. In nuclear accidents, a measure of the type and amount of radioactivity released, such as from a reactor containment failure, is known as the source term.
There is significant radioactive contamination at an elementary school in suburban St. Louis where nuclear weapons were produced during World War II, according to a new report by environmental ...
No high yield (more than c. 10 kiloton) nuclear bombs, including the extreme example of the 50 megaton Tsar Bomba, are able to radiate sufficient neutrons beyond their lethal blast range when detonated as a surface burst or low altitude air burst and so are not classified as neutron bombs, thus limiting the yield of neutron bombs to a maximum ...
