Uranium mainly
Plutonium and Uranium in fission weapons, Lithium deuteride in fusion weapons, occasionally small amounts of Tritium gas to boost fission weapons with fusion.
Plutonium is very useful in nuclear weapons or nuclear fuels but is toxic, radioactive and expensive.
The radioactive elements plutonium or uranium are the elements that are used in nuclear weapons that create nuclear fission. Isotopes of hydrogen are used in nuclear weapons that create nuclear fusion.
Plutonium is very useful in nuclear weapons or nuclear fuels but is toxic, radioactive and expensive.See the link below for more details.
Thorium was not used in nuclear weapons.
Plutonium obtained in nuclear reactors with uranium fuels after recycling of the burned fuels can be used also as a nuclear fuel.
Because plutonium is needed for nuclear weapons and nuclear fuels.
Plutonium is an artificial metal, very toxic, reactive and radioactive. Plutonium is used in nuclear fuels and nuclear weapons.
Plutonium is very useful in nuclear weapons or nuclear fuels but is toxic, radioactive and expensive.
Plutonium is very important for nuclear weapons and for nuclear fuels used in nuclear reactors. But plutonium is also toxic and radioactive. See the link below.
Plutonium is very important for nuclear weapons and for nuclear fuels used in nuclear reactors. But plutonium is also toxic and radioactive. See the link below.
No nuclear weapons were used in the korean war
Plutonium is an artificial element; traces (extremely low) of plutonium isotopes of natural origin exist in uranium ores. Plutonium is used in nuclear weapons and nuclear fuels.
The radioactive elements plutonium or uranium are the elements that are used in nuclear weapons that create nuclear fission. Isotopes of hydrogen are used in nuclear weapons that create nuclear fusion.
Fossil fuels are not used in nuclear power stations. Nuclear fuel is used (uranium)
None. No nuclear weapons were used in Viet Nam.
The Bikini atoll was used for nuclear weapons testing.
Neptunium has only limited uses:- precursor in the preparation of plutonium-238- sensor in the detectors of high energy neutronsIn USA are studied applications of neptunium in nuclear weapons or as nuclear fuels.
