“…This study was conducted in five Eastern Geopolitical Zone (Made up of Abia, Anambra, Ebonyi, Enugu and Imo States). The region lies between longitudes 7° 6" E and 7° 54" E and latitudes 5° 56" N and 6° 52" N. It encompasses an area of about 7161km 2 with elevation ranging from 32.0m to 590.2m above mean sea level (Osimobi et al, 2018). The region has two main landforms viz; a high relief central zone with undulating hills and ridges and lowland area.…”

“…The region has two main landforms viz; a high relief central zone with undulating hills and ridges and lowland area. The high relief zone is geologically associated with the syncline composed of Ajali Sandstone and Nsukka Formation, while the eastern lowland zone is associated with rocks of Asu River group, Eze Aku Shale group, Awgu/Ndeabor Shale group, Asata/Nkporo Shale group and parts of Mamu Formation (Osimobi et al, 2018).…”

“…The radium equivalent (Raeq) activity is the measured number of activities of the natural radionuclides (Radium, Thorium, Potassium) and is established on the proven fact that 1 Bq kg -1 of 226 Ra, 0.7 Bq kg -1 of Th, and Bq kg -1 of K generate equal radiation dose rates (Osimobi et al, 2018). Radium equivalent (Raeq) equates the specific activity levels of the sample contained in the three natural radioactivity ( 40 K, 226 Ra and 232 Th) by a sole amount and account for the radiological risk (Agbalagba et al, 2012).…”

This study examined the radioactivity levels of soil samples within selected solid mining sites in Nigeria using high purity germanium (HpGe) detector. Sixty soil samples in all were collected from the ten solid mineral mining sites investigated and six samples were collected as control samples from non-mining environment for analyses.The results of the activity concentration values obtained for 40 K, 226 Ra and 232 Th are 100.22 Bq kg -1 , 33.15 Bq kg -1 and 77.31 Bq kg -1 respectively. The 226 Ra and 40 K activities were found to be within the United Nation Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) acceptable permissible limit, but the 232 Th mean value was above the permissible limit of 30 Bq kg -1 for the public. In comparison, 40 K, 226 Ra and 232 Th soil samples mean activity concentrations were higher than the control soil samples values by 48.6%, 43.7% and 62.3% respectively. The results of estimated radiation hazard indices indicate average values of 150.72 Bq kg -1 , 68.40η ℎ , 83.65µSvy -1 and 454.70µSvy -1 for the Radium Equivalent (Ra ), Absorbed Dose Rate (D), Dose Equivalent (AEDE) and Annual Gonadal Equivalent Dose (AGED) respectively. The mean values for External Hazard Indices (Hex, Hin), Representative Gamma index ( ) and Excess Life Cancer Risk (ELCR) were 0.41, 0.50, 1.06 and 0.29 x10 -3 respectively. The statistical analysis shows positive skewness.

“…12 Despite the investment of money and resources, the incidence of injuries remained relatively unchanged and the government, companies, employees and society all agreed that it is still unacceptably high. 13 Preventive measures to reduce the burden of these problems must be taken and an accurate assessment and understanding of the risk factors leading to injuries can be a good starting point. The information would be very useful in the planning of strategies/interventions at the workplace by mine managements to reduce occupational injuries.…”

Introduction: The mining industry is known to have a high incidence rate of fatal injuries hence, the knowledge of the risk factors of injury is important. The risk factors of occupational injury are important in the interplay between work and health, and the knowledge of the risk factors can be used in planning preventive measures. The study was done to determine the risk factors for occupational injuries among solid mineral miners. Methods: This was a descriptive cross-sectional study. Consenting staff completed the pretested self-administered questionnaire. Data were analyzed using descriptive and inferential statistics and p ≤ 0.05 was considered significant. Results: A total of 120 workers were recruited with 109 (90.8%) males and 11 (9.2%) females leading the male to female ratio of 9.9:1. The age range was 18-48 years with a mean of 28.9 (5.8) years. More than one-third (35.0%) had a tertiary level of education. Seventy-two (60.0%) had good knowledge of the occupational injury, and it was associated with the level of education (p<0.001) and occupational injury (p<0.001). About 60.8% have had an occupational injury while inhalational injury (30.0%) was the highest type of injury. Hands (34.5%) were the most affected part of the body even though hand gloves (85.8%) were the most common personal protective equipment used. The factors associated with an occupational injury were age, length of services and job tasks. The predictor of occupational injury was the length of service. Conclusion: The respondents had good knowledge of the occupational injury and the major risk factors of occupational injury were the length of services, job tasks and age of respondents of this study.

“…All elements with atomic number greater than 80 possess radioactive isotopes, and all isotopes of elements heavier than number 83 are radioactive (Tailor, 2006;Kragh, 2018;Stacey, 2018). Radiometric evaluation in some selected mining sites is important for the protection of public health especially if the released radionuclides enter the food chain or result in the unnecessary radiation exposure to population (Osimobi et al, 2018). It is globally well accepted that direct ingestion of contaminated soil, inhalation of fugitive dusts, external radiation dose exposure and ingestion of home produce in a residential setting may result in serious health hazard (Abuelhia, 2019).…”

The data for this research contains the in-situ measured activity concentration of radionuclides and gamma-radiation dose rate obtained from the radiometric survey in Azara development area of Awe Local Government, Nasarawa State, Nigeria. The data were manually collected in eight (8) locations with 20 data taken from each point using a portable hand held Thermo Scientific Interceptor and a radionuclide IdentiFINDER. The descriptive statistical analysis of the data was equally explored for possible statistical relationships. The result obtained is made available publicly for further extended analyses that can provide insights into the safety status of the study area from radiological health concerns. The data could also serve as a significant baseline radiometric data for future researches and monitoring initiative in Azara and its environs.
