introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

In this paper, Michael Boyer attempted to determine the magnitude of an emerging environmental threat: the flow of radioactive materials from industrial sites in the former Soviet Union to rivers and other bodies of water, which in turn empty into the Arctic Ocean. While such radioactive pollution is harmful regardless of its destination, the Arctic’s precarious ecology is particularly vulnerab...

Radon and progeny ((218)Po, (214)Pb, (214)Bi and (214)Po) in thermal spas are well known radioactive pollutants identified for additional radiation burden of patients due to the activity concentration peaks which appear during bath treatment or due to drinking of waters of high radon content. This burden affects additionally the working personnel of the spas. The present paper has focused on th...

The simulation of radioactive pollutants dispersion is critical for emergency response of the nuclear terrorism. The radioactive “dirty bomb”, also called radiological dispersion device (RDD), produced and used by the terrorist to make fearful and radioactive pollution in general, has a great risk on humans. Numerical investigation of the impact of different configurations on radioactive pollut...

Standby Gas Treatment System (SGTS) is one of the engineered safety features installed in BWR and ABWR plants to limit the discharge of radioactivity into the environment during the reactor accident. Kl3 impregnated charcoal (iodized charcoal) filter is used for removing of radioactive iodine species such as molecular iodine and methyl iodide. It is well known that the removal capability of imp...

Radioactive waste from different sectors such as nuclear energy, health care and food has become a discernible part of our environment. Several dumping methods are in routine practice to dispose radioactive wastes. Huge chemical and energy input in various skillful physico-chemical methods has limited their use while biological methods exploring the potential of micro-organisms could be a promi...

Modeling the movement and consequence of radioactive pollutants is critical for environmental protection and control of nuclear facilities. Sensitivity analysis is an integral part of model development and involves analytical examination of input parameters to aid in model validation and provide guidance for future research. Sensitivities of 21 input parameters have been analyzed for a specific...

In the eMinerals project we use computational modelling to research mineralogical processes at an atomistic level, providing information on transport and immobilisation processes of pollutants, including radioactive waste. Prior to the eMinerals project most calculations where undertaken on so-called model systems. With the new grid tools, available within the eMinerals project, we are instead ...
