“…However, it is important to mention that although this information is relevant for emergency preparedness, radiation carcinogenesis is a complex phenomenon. The results in Table IV are in agreement with those of Aliyu et al (2014a), which adopt the GENII model for dose calculations on humans.…”

El modelo de dispersión atmosférica de corto alcance (AERMOD, v. 12345) de la Agencia para la Protección Ambiental de Estados Unidos (US-EPA, por sus siglas en inglés) es una buena alternativa para calcular las dosis de radiación que recibe el público general al exterior de instalaciones nucleares, y su avanzada capacidad AERMOD para valorar las descargas atmosféricas rutinarias y accidentales de una nueva planta de energía nuclear (PEN) localizada en Geregu, Nigeria (7º 33' N, 6º 41' W), sobre los cuatro centros urbanos (Ajakuta, Lokoja, Idah y Okene) que se encuentran dentro de la zona delimitada en el plan de emergencia de la PEN. Dicho código ha proporcionado valores para los factores de escala de las concentraciones de radionúclidos utilizaron factores de escala para valorar el posible efecto radiológico externo sobre la biota humana y no humana. Mientras que los efectos radiológicos sobre seres humanos se examinaron mediante los métodos computacionales comunes establecidos por las autoridades regulatorias, respecto de la biota no humana se eligió un enfoque integral para la valoración y manejo de riesgos ambientales debidos a radiación ionizante (D-ERICA). Los resultados de este trabajo indican que, en situaciones de operación normales, la PEN no produce efectos ambientales ni de salud pública importantes. Sin embargo, los accidentes caracterizados por precipitación sí provocarían riesgos radiológicos perceptibles dentro de la zona delimitada en el plan de emergencia de la PEN. ABSTRACTThe United States Environmental Protection Agency (US-EPA) short-range atmospheric dispersion model (AERMOD, v. 12345) is a good candidate for the calculation of offsite radiation doses to the general public, In this paper the AERMOD code has been used to assess the impact of routine and accidental atmospheric radioactive discharges from a new nuclear power plant (NPP) site in Geregu, Nigeria (7˚ 33ˈ N, 6˚ 41ˈ E) on the four major settlements (Ajakuta, Lokoja, Idah and Okene) that lay within the emergency planning zones of the NPP. The code has produced values of the scaling factors for ground level air concentrations and depositions of radionuclides (from the passing plume) over our areas of interest. The scaling factors have been used to assess the potential radiological impact on the offsite human and non-human biota.

“…Exhaust gas diffusion is a complicated process and have attached much attention in recent years (Sharma and Khare 2001;Sagrado et al 2002;Dong and Chan 2006;Kanda et al 2006;Albriet et al 2010;Hathway et al 2011;Aliyu et al 2014;Kim and Baik 2003;Mohamed 2013;Gérardin et al 2014;Carpentieri et al 2011). For a better understand of it, many approaches, such as field observations and measurements, laboratory modeling, and computational fluid dynamics (CFD) model, have been proposed to investigate it.…”

The air pollution induced by urban traffic has addressed much attention in recent years as the rapid urbanization and the fast increase of vehicle number in urban area. In this study, we attempted to investigate the dispersion behavior of exhaust gas from exhaust pipe using computational fluid dynamics approach. The time-averaged CO 2 concentration, velocity and temperature profiles along the centerline of the vehicular exhaust plume were simulated in varied situations. The computational results showed good agreement with the experimental data and the numerical model was validated to be an effective method to investigate the pollutant dispersion in the near-wake region of a vehicle. Based on it, the numerical simulations were extended to explore the impacts of the emit concentration, the emit direction and the incoming velocity on the flow dynamics and CO 2 dispersion. The outputs indicated that the emit concentration could change the pollution level in the near-wake region of a vehicle and the emit direction may alter the spreading direction of the vehicular exhaust plume. The incoming velocity was found to have dominant influence on the dispersion of pollutant due to induced vortices and turbulence behind the vehicle. These findings are expected to provide important insight into evaluating the design and control strategies for alleviating mobile source emissions.

“…to ensure the security and reliability of energy supply; while taking the environmental consequences of energy production into account. Globally, the power sector has been a major contributor of greenhouse gas (GHG) emissions and this has been noted to be due to the dependence of most electricity generating plants on coal and oil [7]. In Malaysia for instance, the power sector is expected to depend more on imported coal in order to meet it's rising energy demand and this has been predicted to result in a situation where the carbon emission profile will be tripled by 2030 compared to its magnitude in 2004 [8].…”
