- 2. a submarine powered by a nuclear reactor, but not necessarily nuclear-armed
- 3. an installation where electrical power is generated for distribution
- 5. use heat produced during atomic fission to boil water and produce pressurized steam
- 6. the process of splitting the nucleus of an atom, releasing energy in the form of electromagnetic waves or energy particles
- 7. an unstable atom that undergoes nuclear fission by emitting particles and energy to become a stable isotope of another element
- 9. power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines
- 10. a technique that measures physiological function by looking at blood flow, metabolism, neurotransmitters, and radiolabeled drugs
- 12. the imaging of body structures, or parts of the body, using x-rays
- 13. a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease
Down
- 1. particles or electromagnetic waves released when radioactive isotopes undergo nuclear fission
- 2. the process of combining nuclei to form a larger nucleus, absorbing or releasing energy
- 4. an environmentally-friendly insect pest control that uses radiation to sterilize the pest.
- 7. radioactive isotopes of an element and atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus
- 8. a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons
- 11. a type of medical treatment of disease, especially cancer, using x-rays or similar forms of radiation
