Radiological safety and environmental monitoring aspects of mining and processing of uranium ore at Jaduguda, India
Low–grade uranium ore is mined and processed in India since the early 1970s. To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. Exposure of occupational workers is evaluated ...

Lead (Pb) on Surfaces by a Portable X-Ray Fluorescence (XRF) Analyzer
This surface sampling method was developed to provide a reliable, portable procedure that will provide prompt measurement of surface contamination levels of lead. Information gained from samples taken during an initial walk-through portion of an inspection may influence decisions regarding the next steps to take, making the inspection more productive. Immediate clearance of clean areas such ...

Accumulated state of the Yukon River watershed: Part I critical review of literature
A consistent methodology for assessing the accumulating effects of natural and man‐made change on riverine systems has not been developed for a whole host of reasons including a lack of data, disagreement over core elements to consider, and complexity. Accumulated State Assessments of aquatic systems is an integral component of watershed cumulative effects assessment. The Yukon River is the ...

Distribution of sterols and the sources of pollution in surface sediments of Ulungur lake, Xinjiang
Domestic sewage discharged into lakes brings great pressure to the ecological environment. This study selected sediment from an inland lake as a research object to evaluate pollution of the environment. Eight sterols were used to evaluate the content of pollutants, while the ratios of sterols were used as the index to analyze the sources of pollution. The correlations were analyzed between ...

Modeling the transport of organic chemicals between polyethylene passive samplers and water in finite and infinite bath conditions
Understanding the transfer of chemicals between passive samplers (PS) and water is essential for their use as monitoring devices of organic contaminants in surface waters. By applying Fick's 2nd law to diffusion through the polymer and an aqueous boundary layer, we derived a mathematical model for the uptake of chemicals into PS from water, in finite and infinite bath conditions. The finite ...
