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 ...
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]
But cleaning up nuclear waste is difficult. It can't be burned or buried. Soon, a waste management plant will turn the waste into glass, which can be stored away for thousands of years.
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.
The Nuclear Waste Policy Act of 1982 established a timetable and procedure for constructing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary storage of waste, including spent fuel from 104 civilian nuclear reactors that produce about 19.4% of electricity there.

56 workers were exposed to about 45 tonnes of radioactive waste which spilled from storage tanks at the Tsuruga Nuclear Power Plant. The waste was cleaned up with buckets and mops, [42] [43] and was also discharged into Tsuruga Bay via the town sewer. [41] At the time, the plant had recorded 30 malfunctions since it was commissioned in 1970. [44] 0
The spent nuclear fuel from uranium-235 and plutonium-239 nuclear fission contains a wide variety of carcinogenic radionuclide isotopes such as strontium-90, iodine-131, and caesium-137. Such waste includes some of the most long-lived transuranic elements such as americium-241 and isotopes of plutonium. [10]
The Windscale fire resulted when uranium metal fuel ignited inside plutonium production piles; surrounding dairy farms were contaminated. [33] [34] The severity of the incident was covered up at the time by the UK government, as Prime Minister Harold Macmillan feared that it would harm British nuclear relations with America, and so original reports on the disaster and its health impacts were ...
