What type of technology is used to provide energy, make bombs, and treat cancer?
Nuclear technology is based on harnessing the energy released when radioactive materials decay.
This energy can be used in a nuclear reactor to generate electrical energy, usually by heating steam and using it to drive a turbine.
If the energy released is used to stimulate more radioactive decay, then that energy used to stimulate even more decay and energy release, it can become explosive. This is what makes nuclear bombs explosive.
Radiotherapy is a method for treating cancer which involves using the energy emitted from radioactive materials to kill cancer cells in an affected patient.
