What are gamma rays primarily used for?

1. Medical imaging

2. Industrial applications

3. Nuclear power plants

4. Lighting

The correct answer is: Nuclear power plants

Gamma rays are primarily used in the context of nuclear power plants primarily for the purpose of detecting and monitoring radiation levels. In these facilities, the presence and measurement of gamma radiation become essential for ensuring safety protocols and regulatory compliance. Gamma rays can penetrate materials and are valuable for detecting radioactive isotopes, which are essential in the nuclear fission process. In medical and industrial applications, while gamma rays have important roles—such as in cancer treatment with radiation therapy and in non-destructive testing respectively—these are not their primary functions. Lighting does not typically involve gamma rays, as it usually relies on other forms of electromagnetic radiation, such as visible light. Thus, the application of gamma rays is most recognized in the context of nuclear power, where monitoring and safety are paramount.
