What device uses controlled nuclear fission to produce new radioactive substance and energy?

Answer 1

Einstein showed that all matter has energy, E = mc2. But that doesn't mean we can release it as nuclear energy. Only materials like uranium and plutonium can be used for that and you won't find those at home.

Actually, virtually everything has some kind of radioactive energy. BUT! Only a little bit. If you are intending to harness this, you would need something very strong- and actually has nuclear energy specifically.

Answer 2

The use of nuclear energy in civilian society is to generate electricity. In the military it is to make bombs (and hopefully not use them). There are also some uses in medicine where radio isotopes can be used for diagnosis and treatment. These isotopes are produced by irradiation in low power reactors which enable short lived radio isotopes to be obtained as required.

Answer 3

Power stations produce electricity fronm nuclear power. Submarines and naval vessels produce propulsion power from the same source.

Nuclear reactors tap nuclear power. So do nuclear weapons.

Answer 4

in nuclear power plants nuclear bombs, for production of electricity, for some medical diagnosis, etc.

Answer 5

A nuclear reactor
