Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
It takes billions of years for uranium to decay into lead. Uranium-238, the most common isotope of uranium, has a half-life of about 4.5 billion years, meaning it takes that long for half of a sample of uranium-238 to decay into lead-206.
A cascade is a long series of identical, successive specific equipments used in the process of uranium enriching in the isotope 235U.
The equation for the alpha decay of plutonium-244 is: [ ^{244}{94}Pu \rightarrow ^{240}{92}U + ^4_2He ]
A bomb containing highly enriched uranium (in the isotope 235U) as explosive.
235 is the approx. atomic mass of the isotope 235U.
Uranium in nature is only about 0.7% 235U. In order to have a chain reaction, the percentage of 235U must be increased by enrichment. The percentages of 235U in nuclear reactors are generally low, about 3% to 5%. For bombs, the percentage is generally 85% or more.
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
The equation for the alpha decay of 235U is: 92235U --> 90231Th + 24He representing the alpha particle as a helium nucleus. 235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
Yes, that's correct. The uranium decay chain ends with the stable element lead-206. As uranium-238 undergoes alpha and beta decay, it transforms through various radioactive isotopes before reaching lead-206, which is stable and not subject to further radioactive decay.
Depending on the isotope: - for 235U: 7,038.108 years - for 238U: 4,468.109 years etc.
You think probably to depleted uranium.Depleted uranium is uranium containing less than 0,2 % the isotope 235U.
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
233U and 235U are two fissile isotopes; but 233U is now more expensive. 238U is only a fertile isotope in nuclear reactors with thermal neutrons.
