Types and Characteristics of Nuclear Radiation

The video explains the three types of nuclear radiation: alpha, beta, and gamma. It details their characteristics, ionising abilities, and penetration ranges. The dangers of radiation, including irradiation and contamination, are discussed, highlighting the risks associated with each type. The video also covers practical uses of radiation, such as in smoke alarms, thickness measurement, and medical imaging.
