Abstract: Radiation levels therefore vary from one region of the world to another. Naturally occurred high background radiation areas, due to the uniqueness of their radiation doses and the populations that inhabit, has always been attracting the attention of researchers from different countries. Early epidemiological studies did not show an increasing trend in cancer incidence in high natural background radiation areas, raising some controversy about the validity of the linear non-threshold hypothesis. This paper presents and discusses the main results of radioactivity level measurements, radiobiological and radiation epidemiological studies conducted in some of the major areas with high natural background radiation areas of the world, such as China, Brazil, India and Iran. It is hoped that research interest will be aroused in the topical issues of dosimetry, epidemiology and radiobiology related to the high natural background radiation areas of the world. Recommendations to address the problems faced at this stage, in order to achieve better research related to high natural background radiation areas. At the same time, the inhabitants of high natural background radiation areas are protected from possible radiation exposure.

Key words: high natural background radiation areas, radiation epidemiology, radiation dose, radiobiology
