Radiological Safety Assessment of Agricultural Soil within the Bitumen Belt of Ondo State Nigeria, Using RESRAD-ONSITE and RESRAD-BIOTA Codes

Luka S. Yani, Gregory O. Avwiri & Chinyere P. Ononugbo · Archives of Current Research International · 2023

Exploration and exploitation of bitumen can create radiation exposure pathways that must be considered in risk management scenarios. RESRAD-ONSITE and RESRAD-BIOTA developed by the US Department of Energy (US DOE) to assess contaminated sites, were used in the present study to pr...

Modelling Leachate Pollution Index and Potential for Selected Municipal Solid Waste Dump Sites: A Case Study

Mamuyovwi Odia, Ify L. Nwaogazie, Eunice O. Nwachukwu & Gregory O. Avwiri · Current Journal of Applied Science and Technology · 2017

Unengineered and uncontrolled dump sites is a threat to human and the environment. Leachate infiltration from Municipal Solid Waste (MSW) posed great threats to surface and groundwater systems. Leachate samples were collected from Niger-Cat (NC), Don-Parkar (DP) and Orhuwhorun (O...
