Abstract: This study aimed at employing radiation detection method to examine the total radiation intensity of 20 identified dumpsites in Abeokuta, the capital of Ogun state in the Southwestern part of Nigeria. The result which is comparable to those reported for environs in Nigeria and the World showed the absorbed dose rate from the dumpsites rangedfrom 12.3 to 49.1 μSv year-1 and the mean annual absorbed dose rate of 36.0 μSv year-1. The results indicated that the observed radiation dose is minimal when compared to Nigeria`s average and the world average but no matter how low; all levels of radiation still constitute a hazard. However, it is recommended that these dumpsites be managed or the wastes be converted to useful raw materials through employment generation.
