RADON EXHALATION FROM GRANITIC ROCKS

Brazilian Journal of Radiation Sciences, 2019
Naturally occurring radionuclides such as radon (222Rn), its decay products and other elements from the radioactive series of uranium (238U and 235U) and thorium (232Th) are an important source of human exposure to natural radioactivity.

Radon‐traced pore‐water as a potential source of CO2 and CH4 to receding black and clear water environments in the Amazon Basin

Limnology and Oceanography Letters, 2018
Groundwater is a primary source of dissolved CO2 and CH4 in Amazonian headwaters, yet in higher order rivers, a groundwater/pore‐water source is difficult to constrain due to the high spatial and temporal heterogeneity of pore‐water exchange.

Control of Groundwater‐Lake Interaction Zone Structure on Spatial Variability of Lacustrine Groundwater Discharge in Oxbow Lake

Water Resources Research
Lacustrine groundwater discharge (LGD) is an important water and nutrient source for lakes. Despite its importance, high‐resolution quantifying the spatial variability of LGD remains challenging.
