All "burned" uranium fuels contain plutonium.
Plutonium is not preferentially found in any climate. Except for negligible traces plutonium is produced in nuclear reactors. There are a few ways that it has escaped or been intentionally released from reactors into the environment:detonation of plutonium fueled nuclear explosives (e.g. 1945 through 1963)safety tests of plutonium fueled nuclear explosives (e,g, 1951 through 1963)fires in nuclear explosives materials and/or assembly plants (e.g. Rocky Flats)nuclear reactor accidents (e.g. Chernobyl and Fukushima)safety tests of experimental nuclear reactor designs
Plutonium .
Plutonium has 20 isotopes (from Pu 228 to Pu 247).
Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
Plutonium react with the majority of nonmetals; plutonium doesn't react with noble gases. Plutonium can form alloys with other metals.
Only trace levels, with the natural trace levels completely swamped out by the manmade trace levels from nuclear fallout (both from above ground weapons tests and the Chernobyl and Fukushima reactor disasters) by a factor of many millions.
Chernobyl fallout! (It's a joke)
fallout from burning graphite mixed with molten reactor fuel.
Because the radiation fallout of the Chernobyl disaster of 1986 resulted in many genetic mutations in species of animals around the power plant, as well as human deformities.
The nuclear fallout from Chernobyl contaminated the ground with radioactive particles, making it unsafe for agriculture and causing long-term health risks. It also contaminated surface water sources, leading to restrictions on fishing and drinking water consumption in the affected areas.
Because the area where Chernobyl is at is very close to the border of Belarus, and they received much of the fallout.
Chernobyl started from an inherently unstable design, it's considered a breeder reactor, really good at making weapons grade plutonium but functionally unstable. The actual incident occurred during testing of the reactor to see how far it could be pushed.
The fallout radius of the Chernobyl disaster varied depending on wind patterns and precipitation at the time of the accident. However, significant radioactive contamination was detected up to 1,000 kilometers (about 620 miles) from the reactor site. The most severely affected areas were within a 30-kilometer radius, designated as the Chernobyl Exclusion Zone, where long-term human habitation is restricted due to high radiation levels.
Approximately 2,600 square kilometers (1,000 square miles) were heavily contaminated with radioactive fallout after the Chernobyl disaster in 1986. This area is still considered unsafe for human habitation and is known as the Chernobyl Exclusion Zone.
It was in the Ukraine, however it affected many countries across Europe and the world
The iodine-131 in the fallout poisons the thyroid gland.
some, but not significantly as the general wind direction at the time was from the southeast. this carried most of the fallout northwest of the burning reactor.
