Which type of radiation has the highest energy level?

Gamma rays possess the highest energy level among the options listed. This distinction is based on their nature and origins. Gamma rays are a form of electromagnetic radiation, similar to X-rays but with much higher energy. They are typically emitted from the nucleus of unstable atoms during radioactive decay processes, including those involving alpha and beta decay.

Gamma rays have very short wavelengths and therefore carry more energy than the particles mentioned in other choices. In contrast, alpha particles consist of two protons and two neutrons and exhibit significant mass but relatively low energy compared to gamma rays. Beta particles, which are high-energy, high-speed electrons or positrons emitted during radioactive decay, have more energy than alpha particles but generally less than that of gamma rays. X-rays have energy levels that can range widely, but they still do not reach the energy levels of gamma radiation.

Understanding the energy levels associated with different types of radiation is crucial for radiation safety, especially in medical and dental settings, as it influences how these forms of radiation interact with matter and their potential biological effects.
