Standardization and difficulties of the thoron exhalation rate measurements using an accumulation chamber

Radiation Measurements, 2008
Abstract Standardization of the thoron exhalation measurements is important for the intercomparison of the results among different laboratories. There are a few important distinctions between thoron (220Rn) and radon (222Rn) exhalation measurements using an accumulation chamber, due to a great difference between radon and thoron diffusion lengths in ...

On the calibration of a radon exhalation monitor based on the electrostatic collection method and accumulation chamber

Journal of Environmental Radioactivity, 2015
The radon exhalation rate can be obtained quickly and easily from the evolution of radon concentration over time in the accumulation chamber. Radon monitoring based on the electrostatic collection method is not interfered with by (220)Rn. In this paper, we propose that the difference between radon and (218)Po concentrations in the measurement cell of ...

Accumulation chamber measurements of methane fluxes: application to volcanic-geothermal areas and landfills

Applied Geochemistry, 2003
Direct measurement of present day CH4 diffuse degassing from the soil represents an effective tool to better estimate the degassing rate of individual sources and to calibrate global Earth degassing estimates. While many data exist on CH4 emissions from ecosystems, agricultural soils and landfills, few estimates of CH4 emissions from volcanic ...

Applicability of the closed-circuit accumulation chamber technique to measure radon surface exhalation rate under laboratory conditions [PDF]

Radiation Measurements, 2020
A layer of phosphogypsum was placed at the bottom of two large volume boxes. This system allowed to measure the surface radon exhalation from phosphogypsum without altering the emitting material.
