Nuclear technologies involve the use of nuclear reactions to generate energy, conduct research, and develop various applications. The most common use is in nuclear power plants, where nuclear fission splits atomic nuclei to produce heat, which is then converted into electricity. This process provides a significant source of energy with low greenhouse gas emissions. In addition to energy production, nuclear technologies are used in medicine, such as in radiotherapy for cancer treatment and nuclear imaging for diagnostics. They also play a role in scientific research, including studies in nuclear physics and radiochemistry, helping to advance our understanding of matter and energy.
