What plutonium isotope is used in reactors?
Pu-239
The most common plutonium isotope formed in a typical nuclear reactor is the fissile Pu-239, formed by neutron capture from U-238 (followed by beta decay), and which when fissioned yields much the same energy as the fission of U-235.
Is plutonium-238 rare?
Plutonium does occur naturally, but at very low concentrations. Indeed, it is all but unobservable, except by very sensitive modern analytical techniques. The reason that plutonium (and other transuranic elements) are so rare in nature is that being radioactive, they decay with a characteristic half-life.
Is plutonium-239 used in reactors?
Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233.
Is plutonium-242 stable?
The most stable are plutonium-244 with a half-life of 80.8 million years, plutonium-242 with a half-life of 373,300 years, and plutonium-239 with a half-life of 24,110 years.
What is Plutonium-238 used for?
What is it used for? Plutonium-238 generates significant heat through its radioactive decay process, which makes it useful as a heat source for sensitive electrical components in satellites, as a well as a power source (for example, battery power) for satellites. Plutonium-239 is used to make nuclear weapons.
What is plutonium 241 used for?
Plutonium-238, which is made in nuclear reactors from neptunium-237, is used to make compact thermoelectric generators; plutonium-239 is used for nuclear weapons and for energy; plutonium-241, although fissile, (see next paragraph) is impractical both as a nuclear fuel and a material for nuclear warheads.
Can I buy plutonium 238?
The United States will buy Russian-produced plutonium-238 for use as a power source in American spacecraft, the Department of Energy has announced. The contract provides for the United States to buy up to 40 kilograms, or about 88 pounds, over five years.
What does plutonium 204 do to the body?
Because it emits alpha particles, plutonium is most dangerous when inhaled. When plutonium particles are inhaled, they lodge in the lung tissue. The alpha particles can kill lung cells, which causes scarring of the lungs, leading to further lung disease and cancer.

What is plutonium-241 used for?
What is plutonium-238 used for?
What is plutonium-244 used for?
Plutonium-244 production at the Savannah River Site (SRS) 2). Its primary purpose was to produce special nuclear materials for national defense, specifically weapons-grade Pu and tritium (3H) required for thermonuclear devices26.
Is Plutonium-238 explosive?
In real life, Plutonium 238 isn’t explosive. In reality, Plutonium-238 isn’t even a fissile isotope; useless for weapons or reactor fuel, it’s solely a source of heat and alpha emitters in scientific research.
How much does Plutonium-238 cost?
When the United States and Russia shuttered their nuclear weapons programs in the 1980s, the world stopped producing plutonium-238. Not surprisingly, plutonium-238 is expensive to make – very expensive. One pound of plutonium-238 costs about $4 million to make.
Can you survive plutonium 204?
However, there is a cure for Polonium-204, but there’s a better chance of recovery if the individual has a lower level of ARS. The biggest risk, in this case, is how the poison will break down the individual’s bone marrow. As a result, the individual could suffer from infections and internal bleeding.
Why is plutonium-239 important?
Plutonium-239 is used to make nuclear weapons. Pu-239 and Pu-240 are byproducts of nuclear reactor operations and nuclear bomb explosions.
Can you buy plutonium-238?
Can I buy plutonium-238?
Where can I buy polonium-210?
And it’s been picked up all over the place. Yes, Polonium-210, “which experts say is many times more deadly than cyanide,” the story notes, “can be bought legally through United Nuclear Scientific Supplies, a mail-order company that sells through the Web.
