ABSTRACT
Radiobiology is the study of the effects of radiation on biological systems. NM professionals use ionizing radiations in the diagnosis and therapy of many illnesses. Acquiring a basic understanding of radiobiology is essential in the practice of their professions, because they must maximize the benefits of their procedures while minimizing the risks of radiation injury to themselves, to patients, to coworkers, and to the public. They must also understand that their professions involve a small risk of exposure to low levels of radiation over many years of practice. Understanding radiobiology will strengthen the reasons for practicing ALARA. Furthermore, the fundamentals of radiobiology will help clarify the reasons for the protocols used in radionuclide therapy.
