Which of the following is a type of radiation?

Radiation can be classified into several different types based on its properties and the way it interacts with matter. The correct choice encompasses all three: beta, gamma, and alpha radiation, which are distinct forms of ionizing radiation produced during radioactive decay.

Beta radiation consists of high-energy, high-speed electrons or positrons emitted from a radioactive nucleus. This type of radiation has a moderate penetration ability, as it can pass through air and human skin but is typically stopped by materials like plastic or aluminum.

Gamma radiation, on the other hand, consists of high-frequency electromagnetic waves. Gamma rays have a much higher penetration capability than either beta or alpha particles, allowing them to pass through most materials, including the human body. Their high energy makes them particularly hazardous, necessitating strong shielding such as lead or several centimeters of concrete.

Alpha radiation involves the emission of alpha particles, which are composed of two protons and two neutrons. While alpha particles have low penetration ability and cannot penetrate human skin, they can be extremely harmful if ingested or inhaled due to their strong ionization capability.

Since all three types of radiation—beta, gamma, and alpha—are indeed different forms of radiation, the correct answer includes all of them. Understanding these types and their properties
