Gamma (γ) radiation are fast moving
Correct answer: C. Photons
- A. Electrons
- B. Protons
- C. Photons
- D. Neutrons
Explanation
The explanation is given below: Gamma (γ) radiation consists of high-energy photons, which are particles of electromagnetic radiation. These gamma photons are indeed fast-moving and travel at the speed of light. They have very high energy and short wavelengths, making them the most penetrating and energetic form of electromagnetic radiation. Gamma radiation is produced in various nuclear processes, such as radioactive decay and nuclear reactions, and it is a significant form of ionizing radiation used in a variety of applications, including medical imaging and radiation therapy, industrial inspection, and scientific research.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
