Health physics or the science of radiation protection is the profession devoted to protecting people and their environment from potential radiation hazards while making it possible to enjoy the beneficial uses of radiation.<br><br>The use of radiation in medicine, industry and research offers countless benefits. To ensure that radiation and radioactive materials are used safely, nuclear facilities and research laboratories demand personnel who understand the many types of radiation hazards and how to prevent and control them. Specialized education and training is a prerequisite for becoming a professional health physicist. To qualify for professional status, a health physicist needs at least a bachelor's degree in science, engineering or health science with specialized courses in physics, mathematics, chemistry, nuclear engineering, radiation biology, radiological health and occupational health. A graduate degree in health physics is required for many professional-level positions, particularly for those involving health physics research or teaching.
