This program take a thorough look at nuclear radiation, covering the history of its discovery, what makes atoms radioactive, and methods for detecting radioactivity. The video also explains types of radiation including alpha, beta, gamma, and positron, types of decay and decay equations, decay series, radiation dose, and dose equivalence. The effects of radiation on living things and the environment, and the uses of radiation in medicine and industry are also discussed, with application to real-life situations.
