Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. [1] The storage and disposal of radioactive waste is regulated ...
Long-term nuclear waste warning messages. 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 interdisciplinary field of research, first established by the American ...
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.
Nuclear power has at least three waste streams that may impact the environment: [8] Spent nuclear fuel at the reactor site (including fission products and plutonium waste) Tailings and waste rock at uranium mining mills. Releases of ill-defined quantities of radioactive materials during accidents.
"It's the most dangerous stuff [nuclear waste] in the whole country," she said. "It's hot, high-level toxic waste". Another visitor, Keith Spencer, was less concerned. "It wouldn't put me off ...
Spent nuclear fuel stored underwater and uncapped at the Hanford site in Washington, US. About 1% of the mass is 239 Pu and 240 Pu resulting from conversion of 238 U, which may be considered either as a useful byproduct, or as dangerous and inconvenient waste.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. [6]
