Environmental impacts of waste produced from processing of different uraniferous rock samples
Journal of Radiation Research and Applied Sciences, 2016 Radon exhalation rates from five studied laboratory waste samples resulted from five different sedimentary rock types named sandy dolostone, siltstone –two samples-, marly claystone and black shale were measured using ‘‘Sealed Can technique”. These rates

Diurnal and semidiurnal cyclicity of Radon (222Rn) in groundwater, Giardino Spring, Central Apennines, Italy [PDF]
, 2018 Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including earthquakes. In this work, Rn concentrations in groundwater were

The Nylon Scintillator Containment Vessels for the Borexino Solar Neutrino Experiment [PDF]
, 2007 Borexino is a solar neutrino experiment designed to observe the 0.86 MeV Be-7 neutrinos emitted in the pp cycle of the sun. Neutrinos will be detected by their elastic scattering on electrons in 100 tons of liquid scintillator. The neutrino event rate in

Numerical Investigation on Flow Separation Control of Low Reynolds Number Sinusoidal Aerofoils [PDF]
, 2016 The paper presents a computational analysis of the characteristics of a NACA 634- 021 aerofoil incorporated with sinusoidal leading-edge protuberances at Re = 14,000. The protuberances are characterized by an amplitude and wavelength of 12% and 50% of

Geologic and climatic controls on the radon emanation coefficient
Environment International, 1996 Abstract Geologic, pedologic, and climatic factors, including radium content, grain size, siting of radon parents within soil grains or on grain coatings, and soil moisture conditions, determine a soil's emanating power and radon transport characteristics.

Constraining Radon Backgrounds in LZ [PDF]
, 2017 The LZ dark matter detector, like many other rare-event searches, will suffer from backgrounds due to the radioactive decay of radon daughters. In order to achieve its science goals, the concentration of radon within the xenon should not exceed $2\mu$Bq ...

Testing an Online Spread Pattern Determination Sensor on a Broadcast Fertilizer Spreader [PDF]
, 2002 An alternative method for fertilizer spread pattern determination was developed based on predicting where individual fertilizer particles land on the ground, in contrast to the traditional method of collecting the particles in bins (ASAE Standard S341.2).
