However, the whole spectrum ofelectromagnetic radiations has been practically unchanged since theBig Bang. As a matter of fact, the cosmic microwave backgroundradiations from the time of the Big Bang still linger around the wholeuniverse. From these radiations, astrophysicists can measure andcalculate the authenticity of the Big Bang theory.This book will take you through the creation of the atom bomb and itsunimaginable destructive power. It will pass through the end of WWII, the time in which scientists came to their senses and dedicated theatomic industry to humanitarian efforts--such as lighting up thousandsof cities and saving millions of lives in the medical field. In thefinal chapter, there is an emphasis on some of the procedures donein departments of nuclear medicine in order to familiarize collegestudents, the public, and patients who may need
