Abstract
Radioactivity from natural sources is very important from environmental stand point because it represents the major collective dose of the world population. It is very difficult to
carry out this type of assessment especially in the developing countries because the available data are not enough to perform it. In order to carry out the assessment of radiation doses for Abu Qir (Alexandria) and Edku city (Behara), a comprehensive study is preformed. This study was carried out in four stages.
