Radiation Doses Due to Natural Radioactivity in Selected Areas in Southern Part of Jordan

The present study introduces some data regarding Radiation Doses Due to Natural Radioactivity measured the investigations we have already carried out in Selected Areas in Southern Part of Jordan. The investigated area, which is 270 Km long, includes three governorates in Jordan: Tafila, Ma'an, and Aqaba. These data emphasis on new findings of different radiation dose rates, to mainly identify the potential and known impacts of exposures in these areas of this part of the country on public health, and also to make recommendations for further studies. A significant part of the total dose contribution in the form of natural sources comes from terrestrial gamma radionuclides. The measured absorbed dose rates in air were in the range of 10 –200 nSv/ h. The lowest absorbed external dose rate was on the water body of Gulf of Aqaba, while the highest was on the highway of the industrial zone south of Aqaba.
