“…Also, the soil radionuclides’ activity concentrations were comparable to other related studies conducted within and outside Nigeria. 4, 43 - 51 Eke et al 4 and Olagbaju et al 51 obtained lower activity concentrations of 226 Ra ( 238 U) compared to the present study. Egunyinka et al 42 and Ugbede et al 47 recorded higher activity concentrations of 226 Ra ( 238 U) compared to the present study.…”

A total of 30 soil samples from different sampling points at Imo State University (IMSU), Owerri, Nigeria were collected for the study. The activity concentrations of naturally occurring radionuclides (238U, 232Th, and 40K) were measured in the samples by gamma-ray spectrometry using NaI (TI) detector. Absorbed dose rate (D), annual effective dose (AED), radium equivalent activity (Raeq), and radiological hazard index parameters (activity utilization index [AUI], external hazard index [Hex], internal hazard index [Hin], and excess lifetime cancer risk [ELCR]) due to the naturally occurring radionuclides were determined. The mean activity of 238U, 232Th, and 40K were found to be 20.32 ± 3.22, 22.55 ± 0.68, and 91.63 ± 1.54 Bqkg−1 which were lower than the world average reference mean values of 33, 45, and 420 Bqkg−1for 238U, 232Th, and 40K, respectively, as reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). The average value of D, Raeq, AUI, ELCR, Hex, and Hin in the soil samples was 26.86 ± 1.97 nGyh−1, 59.62 ± 4.14 Bqkg−1, 0.42 ± 0.03, 0.14 ± 0.01 (×10−3), 0.16 ± 0.01, and 0.22 ± 0.02, respectively. The annual effective dose to the general public was 33.07 ± 2.40 μSvy−1. This value lies well below the average worldwide reference value of 0.7 mSvy−1, as reported by UNSCEAR. Soil samples from IMSU pose no significant radiological health hazards to the university community.

“…The higher levels of background radiation are associated with volcanic rock masses (granite), and lower levels with sedimentary rocks (Stojanovska et al, 2016;Abba et al, 2017) and Quaternary geological background (Sanusi et al, 2014).…”

This study deals with the results of measuring the ambient dose equivalent rates conducted in test field. The impacts of temporal and weather variations (wind, precipitation, moisture, temperature) as well as spatial characteristics (rural and urban sites) on the ambient dose equivalent rate were analyzed. Mean ambient dose equivalent rate in rural site (142 nSv/h) is higher than in urban site (128 nSv/h). The reason is difference in altitude and also the difference in the local geology. Although an increasing of temperature, decreasing the moisture in air, and slowing down the wind speed during the observed period showed tendency of stability the ambient dose equivalent rate, no correlation was found between ambient dose equivalent rate and any parameter.
