Define chain reaction (in terms of a nuclear fission reaction) -______________________________________________________________

• A process in which atomic nuclei combine to form heavier nuclei
• A process in which atomic nuclei remain stable and do not undergo any change
• A process in which the neutrons released by the splitting of atomic nuclei produce additional fission events, which in turn release more neutrons and so on.

• A process in which atomic nuclei decay into lighter nuclei

Why is gamma radiation used for imaging the human body instead of alpha or beta radiation?

• Gamma radiation has higher energy and can penetrate deeper into the body.
• It is not. Alpha and beta radiation are used in medical imaging instead.

• Alpha and beta radiation have higher energy and can cause more damage to the body.
• Alpha and beta radiation have lower energy and cannot penetrate deep into the body.
