Radioactive Emissions and Their Properties

The video tutorial explains the three types of radioactive emissions: alpha particles, beta particles, and gamma rays. Alpha particles are helium nuclei with high ionizing power but low penetration. Beta particles are high-speed electrons with moderate ionizing and penetrating power. Gamma rays are electromagnetic waves with low ionizing power but high penetration. Each type of emission has distinct properties and effects on materials they pass through.
