7Be/210Pbxs Ratio-Derived Age and Residence Time of Suspended Sediments in Galveston Bay

Frontiers in Marine Science, 2021
The winds associated with the passage of meteorological fronts cause waves that induce sediment remobilization/resuspension, especially within shallow estuaries such as Galveston Bay.

A multi-year study of radioactivity in surface air and its relation to climate variables in Belgrade, Serbia [PDF]

Nuclear Technology and Radiation Protection, 2013
Activities of 7Be and 210Pb were monitored in surface air in Belgrade, Serbia, from 2004 to 2012. The measurements were taken from two locations, in an open field of a city suburb and in the central city area.

Resuspension, Redistribution, and Deposition of Oil-Residues to Offshore Depocenters After the Deepwater Horizon Oil Spill

Frontiers in Marine Science, 2021
The focus of this study was to determine the long-term fate of oil-residues from the 2010 Deepwater Horizon (DwH) oil spill due to remobilization, transport, and re-distribution of oil residue contaminated sediments to down-slope depocenters following ...

Determination of correction factor of self-absorption for lead-210 in environment samples using spike method [PDF]

E3S Web of Conferences, 2021
In environment radiation measurement, calculation the correction factors are critical, especially for low energy measurement because of self-absorption phenomena. In this work the main purpose is to determination the self-absorption correction factors of

Lead-210 in Tobacco and Cigarette Smoke [PDF]

Public Health Reports (1896-1970), 1967
M ANY recent investigations of cigarette smoke have been concerned with concentrations of polonium-210 and the radiation dose to the lungs of smokers who inhale it (1, 2). To ascertain if further insult to the lungs occurs, a study of the levels of other radionuclides, specifically lead-210 in cigarette smoke, was undertaken at the Northeastern ...

Dosimetry and Calorimetry Performance of a Scientific CMOS Camera for Environmental Monitoring

Sensors, 2020
This paper explores the prospect of CMOS devices to assay lead in drinking water, using calorimetry. Lead occurs together with traces of radioisotopes, e.g., 210Pb, producing γ-emissions with energies ranging from 10 keV to several 100 keV when they ...

Volume reduction of water samples to increase sensitivity for radioassay of lead contamination

Applied Water Science, 2022
The World Health Organisation (WHO) presents an upper limit for lead in drinking water of 10 parts per billion ppb. Typically, to reach this level of sensitivity, expensive metrology is required.
