Uranium-238 is fissionable. Its just not what we call fissile, which has the added definition of, when fissioned, producing neutrons that can go on to fission more atoms. Uranium-238 is more correctly called fertile, which means that a neutron can transmute it into another isotope, such as plutonium-239, which is fissionable and fissile.
Uranium-235, on the other hand, is both fissionable and fissile.

What particles does plutonium give off?
Plutonium is especially an alpha particles emitter.
What is the appreciable radioactivity of uranium is mainly due to m?
Uranium natural isotopes emit alpha particles, gamma radiations, beta radiations and spontaneous fission neutrons.
Does uranium give of invisible rays?
Yes, uranium isotopes emit alpha particles, gamma rays, beta rays, spontaneous fission neutrons.
What are the alpha particles in the environment?
Naturally occurring alpha particles are mostly from cosmic radiation and radioactive isotopes such as Americium and Uranium.
How uranium effect your environment?
Uranium undergoes radioactive decay and emits alpha particles which can damage tissue.
Uranium 235 and Uranium 238 are said to be what kind of radioactivity?
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
What substance does uranium and plutonium release?
The elements emit especially alpha particles.
When uranium radiate alpha particles what element is produced?
Thorium isotopes are obtained.
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What is correct about Depleted Uranium DU?
clothing and skin will block the majority of the alpha and beta particles.
What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''

What particles does plutonium give off?
Plutonium is especially an alpha particles emitter.
What were the rays emanating from uranium?
* Alpha rays (particles) * Beta rays * Gamma rays * Spontaneous fission neutrons
