[Investigation of cancers incidence relevant to radiation in Chaharmahal and Bakhtiari province during five years [1998-2002]]

ABSTRACT

Background and Aim: the induction of cancer appears to be the most important effect of low-dose ionizing radiation occurring in an exposed population. The major cancers induced by whole-body radiation exposure are the breasts in women, thyroid, lung, skin cancers and leukemia. In developing countries 94% of the human radiation is from the natural sources. In Iran some high altitude regions such as Chaharmahal and Bakhtiari has a high level of the natural background radiation [higher than the world's average]. For this reason, investigation of the incidence of cancer, relevant to the radiation is very important in this province which is the aim of this study
