Abstract: In this research, the authors employed radiation detection methods to examine the radiation intensity or exposure at 5 quarry sites and their respective neighborhood villages in Ogun State of Nigeria. The highest annual dose rate or exposure of 49.1 �Sv year 1 was recorded at Equation Limited (Q3) in Obafemi Owode Local Government area in Ogun State of Nigeria. However, this result (49.1 �Sv year 1) and others from the remaining locations or sites are smaller than the world average of 70 �Sv year 1 but recommended that workers at quarry sites should always put on masks to eliminate or reduce the amount of radioactive inhalation. Regular comprehensive monitoring of radiation level of each worker by putting on Thermo Luminescent Dosimeters (TLDs) which could be read and interpreted must be encouraged.
