Description
The knowledge on radioactivity contents of various radionuclides in rocks plays an important role in health physics and geo-scientific research. The naturally occurring radionuclides226Ra, 232Th and 40K are the main sources of radiation in soil and rocks, from which traditional building materials are derived. These radionuclides pose exposure risks externally due to their gamma-ray emissions and internally due to radon and its progenies, which emit alpha particles. The activity concentration (Bq/Kg) in igneous and metamorphic rock samples from different locations in Egypt and Germany has been analysed. Concentration values were found in the range of 3.9 : 57.4, 3.2 :53.4 and 202 :1211 for 226Ra, 232Th and 40K in Egypt while it were 5.1 : 76, 3.4 :70 and 10 : 2070 for samples in Germany. Even though these radionuclides are widely distributed, their concentrations depend on the local geological conditions
