| Popis: | The outdoor gamma radiation dose rates due to natural radioactivity and due to the artificial radionuclides released from the Chernobyl and Fukushima accidents and Algeciras incident were assessed in the Algiers province (capital of Algeria). Furthermore, the dose rates induced by the cosmic rays were analytically calculated in the province concerned. The recorded dose rates due to terrestrial outdoor gamma radiation were found to range from 14.3 ± 0.7 to 114.3 ± 5.7 nGy h −1, those due to cosmic rays ranged from 32.021 ± 0.013 to 34.029 ± 0.367 nGy h −1, while the contribution of the dose rate due to external exposure induced by 137Cs deposits, from major accidents, was estimated to be less than 0.3 nGy h−1. The spatial distributions of terrestrial and cosmic rays dose rates were mapped using QGIS software. The obtained radiological baseline maps can be used as reference information to assess any changes in the radiation exposure levels having an impact on the population health. |
