1. Uranium is a possible polluting agent of the natural environment.
2. Uranium is a toxic and a radioactive chemical element.
3. Uranium release radium and radon.
4. Radioactive wastes are dangerous and need to be isolated.
Plutonium: the same characteristics, but it is more toxic and radioactive.
Hydrogen: it is a cause of severe explosions.
Uranium, plutonium or hydrogen.
The critical mass of plutonium is lower, plutonium is not so expensive as highly enriched uranium, the technology to obtain plutonium is more simple than the isotopic separa-tion of uranium, etc.
A uranium bomb is an atomic bomb fueled by uranium-235A plutonium bomb is an atomic bomb fueled by plutonium-239A composite bomb is an atomic bomb fueled by both uranium-235 and plutonium-239A wet bomb is a hydrogen bomb fueled by liquefied deuterium/tritiumA dry bomb is a hydrogen bomb fueled by solid lithium deuteride
Uranium and plutonium can form alloys.
Plutonium and uranium can form alloys.
Plutonium is more dangerous: the specific activity is greater, the critical mass is smaller, the chemical toxicity is greater.
Plutonium-239 is generally considered more dangerous than uranium-235 because it is highly toxic and poses a greater risk of radiation exposure. Plutonium-239 is a significant nuclear proliferation concern due to its use in nuclear weapons.
Yes, it is possible to recycle "burned" uranium and plutonium.
The atomic radii of uranium and plutonium are identical.
Plutonium is obtained from uranium irradiated in nuclear reactors, consequently the production of plutonium depends on uranium resources.
The masses of the nucleons are independent from the type of nucleus.
in reactors: yellowcake, a uranium oxide; after that probably metallic uraniumin stars: ordinary hydrogen; after that helium
