RSP (Radioecological Software Package) is an interactive support system that simulates the behaviour of radionuclides in semi-natural environments and the consequences on the population in terms of the external exposure. RSP consists of three modules: the first one, soil mobility, simulates the vertical transport of radionuclide in soil using the mathematical model RABES. The second module, soi...

A multi-layer one-dimensional vertical model of the upper soil, vegetation and lower atmosphere is developed and implemented. This model includes explicit representations of the heat and moisture diffusion both in the soil and in the atmosphere, and computations of various mass and energy fluxes at the soil-air, vegetation-air and soil-root interfaces. Four models are run in parallel to compute...

A comparison of the invasion of flowers, aerial pegs, and kernels by wild-type and mutant strains of Aspergillusflavas or A. parasiticus along with aflatoxin analyses of kernels from different drought treatments have supported the hypothesis that preharvest contamination with aflatoxin originates mainly from the soil. Evidence in support of soil invasion as opposed to aerial invasion was the fo...

In this study 222Rn (Radon) measurement were performed in water and soil gas and also both 222Rn and 220Rn concentrations were determined in air of Mansa and Muktsar district of Punjab, India. The data then used for calculation of the annual effective dose for health risk assessment of public. Totally 35 locations have been selected for the measurements. All measurements (222Rn and 220Rn) were ...

In order to identify radon-prone areas and evaluate radon risk level, a soil gas radon survey combined with gamma-ray spectrometry measurements was carried out in Shenzhen City, south China. Meanwhile, the statistical analysis was applied to evaluate the distribution of measured results. This paper presents the methodology of the radon risk assessment. A radon risk map was accomplished based on...

Soil moisture exhibits spatial and temporal variability. Spatial variability is mostly associated to climatology patterns, topography, soil texture, and vegetation index; where as, temporal variability is primarily associated to rainfall and air temperature events. The spatial variability is modeled by a long-term memory model whereas the temporal variability by a short-term memory model. The l...

Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

Predicting infiltration rates is among the most important aspects in planning, designing, and managing groundwater recharge systems, flood water retention basins and other infiltration systems. Knowledge of soil infiltration rates determines the capacity of the soil to receive water and ultimately how much land surface will be required to meet the infiltration demand of the engineered system. T...

The Rn and Rn enter the atmosphere mainly by crossing the air interface of either soil-air or building materials. The existence of relatively high indoor concentration maintains a large Rn, Rn concentration gradient between the materials and open air. The present paper deals with the experimental measurement of Rn, Rn concentrations and the associated inhalation dose rates due to them in the dw...
