ABSTRACT
Alan Turing's words that science is a differential equation seem quite true in the physics of radioactivity. This chapter begins with a differential equation called the radioactive decay law and ends with equations for specific decay processes in the unstable nucleus including alpha decay, beta decay and gamma decay. Throughout the chapter, we give mathematical derivations, equations and example calculations which enable us to make sense of (theory) and make use of (applications) the results of nuclear experiments.
