摘要：

The average annual effective dose equivalent and the collective effective dose equivalent have been determined from measurements of the concentrations of K-40, U-238 and Th-232 in top soil in and around the city of Lagos using in situ gamma spectrometry. The average outdoor absorbed dose rate was (0.041 +/- 0.012) mu Gy.h(-1) resulting in an annual average effective dose equivalent of 50 mu Sv.y(-1). The collective effective dose equivalent to the population in the city is 2.84 x 10(2) man.Sv.y(-1).
