Plutonium is not related to uranium isotopes radioactive decay; plutonium is obtained by nuclear reactions from uranium isotopes only in nuclear reactors.
Yes, plutonium-239 emits alpha particles by decay.
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
First off, it's better to be more careful in regards to the word element. What you actually mean is isotope. The difference is subtle, but important. If I had a large rock of Uranium ore that was just mined, you could say I had the element Uranium. However, the element is made up of a certain percentage of isotopes, those being a nucleus that has the same number of protons, 92 in this case, but different numbers of neutrons.Secondly, alpha decay is defined as the spontaneous emission of a helium 4 nucleus from an isotope, so one of your two resulting elements when alpha decay is involved is always going to be helium. The other element is found by simply subtracting 2 from Pu's atomic number, which is 94, giving you the resulting element's atomic number, which is 92, otherwise known as uranium, specifically, the isotope U 234.
The equation for the alpha decay of 233Pu:94233Pu --> 92229U + 24He2+where the alpha particle is represented as a helium nucleus.Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
Yes, plutonium-239 emits alpha particles by decay.
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
Plutonium 238 is an alpha emitter; the decay product is uranium 234.
Plutonium 238 is an alpha emitter; the decay product is uranium 234.
Plutonium is especially an alpha particles emitter.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
Uranium-235 and plutonium-239 release alpha, beta, and gamma rays during the process of radioactive decay. Alpha particles are helium nuclei, beta particles are high-energy electrons or positrons, and gamma rays are electromagnetic radiation.
plutonium-239
This is an alpha decay.The half-life of uranium-238 is 4,468.10ex.9 years.
When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
Uranium 238 is transformed in thorium 234 by alpha decay.
