A module on radioactivity and nuclear physics. Coverage of radioactivity, including some properties of radioactive nuclei, half-life, ionization, and the use of a G-M tube as a detector. Simple analysis of counting errors is also included. Prerequisites are elementary electrostatics, knowledge of current and voltage, and mechanical energy. Although students who have completed other modules in mechanics and electricity should meet the prerequisites, the prerequisites can be covered in a short introductory lecture. Part of the Physics of Technology program, a 27-module introduction to physics at a pre-calculus level. The American Institute of Physics coordinated this program in the 1970s, with modules created by Florissant Valley Community College, Oak Ridge Associated Universities, the State University of New York at Binghamton, and TERC. From the Instructor’s Manual : The geiger counter is the basis for discussions of radioactivity and nuclear processes. Section A includes elementary observations with a geiger counter, an introduction to statistical analysis of data, and an experiment demonstrating counting losses that can be ascribed to the resolving time of the counter.
