Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population.A low-background Pb-shielded gamma spectroscopic counting assembly utilizing swisse high strength magnesium powder berry NaI (Tl) detector was employed for the measurements.The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples.The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits.

It suffices to say, that lorenametaute.com contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged.Therefore, the environmental matrices around the factory could be used without any restrictions.
