What type of radiation is known for being the most penetrating?

Gamma radiation is recognized for its high penetrating power, making it capable of passing through various materials including human tissue, metals, and concrete more effectively than other types of radiation. This is primarily due to its nature as electromagnetic radiation with high energy and short wavelengths.

In contrast, alpha radiation consists of heavy charged particles that can be stopped by a sheet of paper or even the outer layer of human skin, making it the least penetrating. Beta radiation, while more penetrating than alpha particles, can still be blocked by materials like plastic or glass. X-ray radiation is quite penetrating as well, but gamma radiation typically has greater penetration capabilities due to its higher energy. Understanding these differences is crucial for safety measures and protection strategies in environments where radiation exposure may occur.
