Lesson-16.1.3- know that alpha (??) particles, beta (?????) particles, and gamma (??) rays are ionizing radiations emitted from unstable nuclei in a random process.PreviousLesson-16.1.5- practical: investigate the penetration powers of different types of radiation using either radioactive sources or simulations.Next
