Types and Properties of Radiation

The video tutorial explains the three types of radioactive radiation: alpha, beta, and gamma. It covers their charges, masses, and penetrating powers. Alpha radiation has a positive charge and a significant mass, but low penetration. Beta radiation has a negative charge, low mass, and moderate penetration. Gamma radiation is neutral, has no mass, and high penetration. The tutorial also discusses how these radiations are deflected in electric fields and can be emitted simultaneously during nuclear decay.
