Radioactivity and Nuclear Energy: The Three Types of Nuclear Radiation

The video tutorial explains the differences between alpha, beta, and gamma radiation. Alpha radiation involves the emission of helium nuclei, known as alpha particles, which are positively charged and larger than beta particles. Beta radiation occurs when a neutron decays into a proton, neutrino, and a beta particle, which is a high-energy electron with a negative charge. Gamma rays, the most penetrating form of radiation, are electromagnetic energy with no mass or charge, characterized by short wavelengths and high frequencies.

What are alpha particles and how are they formed?

How do the sizes of alpha, beta, and gamma particles compare?

Explain the process of beta radiation and what it produces.

Describe the characteristics of beta particles.

What distinguishes gamma rays from alpha and beta radiation?
