Environmental Control Systems for Defining the Activity Size Distribution of Radioactive Aerosols - a Case Study
نویسنده
چکیده
The 1ACFM cascade impactor and the High Volume cascade impactors are the instruments that mainly used to define the activity size distribution of radioactive aerosols in the environmental air. The impactors are instruments designed to collect and separate particulate matter according to its aerodynamic size, determining the penetration of particles in the human lung, as well as the transport and diffusion of particles in the ambient air. An example of the activity size distribution of the natural radionuclide tracer Be is given, as this determined by a 20cfm cascade impactor.

Defining Robust Recovery Solutions for Preserving Service Quality during Rail/Metro Systems Failure
In this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. Indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. In this context, the use of rail simulation is vital: for e...

متن کاملInvestigating the effect of rainwater catchment systems on the vegetation characteristics of arid areas (Case study: Tasuki region of Sistan)
Excessive use of water and soil resources, especially in arid and semi-arid regions, increases soil erosion, destructive storms, the occurrence of dust, and desertification. Therefore, to prevent environmental problems in these areas, it is necessary to efficiently manage water and soil resources in arid and semi-arid regions. Rainwater catchment systems are one of the management and operationa...
متن کاملRadiological dose assessment of naturally occurring radioactive materials generated by the petroleum industry in wildlife: A case study of chinkaras of Lavan Island, Iran
Human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (NORM) in by-product and waste streams. Iran has been among the top five oil producing countries since 2005. This high production rate emphasizes the importance of NORM management to ensure the safety of humans and wildlife. Petroleum storage and transport facilities are lo...
