Question

A radioactive nuclide emits $\gamma$-rays due to:

• A. K-electron capture
• B. nuclear transition from higher to lower level
• C. presence of greater number of neutrons than protons
• D. presence of greater number of protons than neutrons

Answer 1

The correct option is B nuclear transition from higher to lower level

Gamma radiation, refers to electromagnetic radiation of an extremely high frequency and are therefore high energy photons. Gamma rays are ionizing radiation, and are classically produced by the decay of atomic nuclei as there is transition occurs from a high energy state to a lower state. The process is known as gamma decay.
