This technical specialty course is one of thirty-five courses designed for use by two-year postsecondary institutions in five nuclear technician curriculum areas: (1) radiation protection technician, (2) nuclear instrumentation and control technician, (3) nuclear materials processing technician, (4) nuclear quality-assurance/quality-control technician, and (5) nuclear reactor (plant) operator trainee. This course, Radiation Physics, contains six modules: Introduction to Radiation Laboratory Safety, Basic Radiation Detection and Measuring Equipment, Atomic Structure and Radioactivity, Radioactive Decay and Half-Life, Decay Processes and Schemes, and Basic Properties of Gamma Radiation. Each module follows a typical format including the following sections: introduction, module prerequisites, objectives, subject matter, exercises, materials, procedures, data tables, reference materials, and tests. (A master index and suggested program planning guides are also available--see CE 026 856 and CE 026 639-643.) (LRA)
