Michael Reimer. Short-term temporal variations of soil gas radon concentration have been studied using different measuring techniques—instantaneous methods (grab sampling) using Lucas cells, continuous monitors, and integral nuclear track-etch detectors.

A relatively Cited by: A general rule of thumb used in the radon profession is that one requires roug times the radon-in-water concentrations per m 3 of water (i.e.

This allowed a direct comparison of the relationship of soil radon flux, as measured by the H-type chambers, with actual indoor radon concentrations measured in the home.

A spectrum of radon concentrations in soil gas obtained by a barasol detector with meteorological parameters such as temperature, barometric pressure and rainfall for the period of August through December at the Stivos area in the Langadas Basin, Northern Greece (Papastefanou Short-term fluctuations in barometric pressure al., ) is illustrated in Fig.

since as the barometric pressures are lowered, the soil-gas Rn concentra- tions increase, and as the barometric pressures rise air is forced into the soil lowering the soil-gas Rn content (Fig.

4).Cited by:   Short term variation of radon concentration in borehole air coincided with the atmospheric pressure changes. The strong impact of rainfall on radon concentration values was observed both in air and water environments.

The decrease of radon content in borehole air and water followed radioactive decay law exclusively in spring and summer by:   (a) Radon and fracture water time-series. (b) Classical spectrograms as a function of time. Barometric tide S 2 (with S 2 > S 1) appear only in atmospheric pressure and fracture water flow rate signals.

A clear S 2 line appears for the atmospheric pressure, fracture water flow rate and radon measured by Cited by: High-quality, representative, and reproducible measurements of soil gas, groundwater, and indoor air contaminant concentrations from VI sites are needed to measure vapor attenuation, verify that VI model predictions are accurate, improve understanding of the operating physical phenomena of VI, and help EPA, states, and other practitioners.

Environmental Protection Agency Research Triangle Park. The entry potential of radon, E (Bq/Pa-s), may be defined as the mass transfer of radon found near the substructure surfaces, C (Bq/m3), with the prevailing pressure -normalized flow of soil gas into the building (soil gas entry potential): £ = CC • [9] Similar to the soil gas entry potential, the radon entry potential should indicate.

atmospheric air [1]. Migration of radon between the lithosphere and atmosphere results from the molecular diffusion that is caused by concentration gradient and on the other hand from convection motion of radon caused by pressure gradient [2, 3, 4].

Radon. Sometimes daily or even hourly measurements are warranted, as in time domain reflectometry measurements of soil moisture in evapotranspirative caps, where modeling tries to capture daily fluctuations in near surface water content caused by fluctuations in temperature, solar radiation, barometric pressure, and precipitation.

At the bottom of the well, pressure equals the weight density of water times the height of the water column H, P = ρw gH = N/m3 × m = × N/m2 Since the pressure at the top of the well is zero, the change in pressure from top to bottom is dP = × N/m2.

With two expeditions organized in October and Septembera complete survey of the cave was performed using laser scanning equipment (a Leica HDS in and a Leica P40 in ).

The installation of barometric, temperature and humidity dataloggers in different areas of the cave have provided a one-year data record of the microclimate. developed It was observed that soil-gas and gas exhalations in general are commonly enriched in Rn in fault zones and that the near surface-air shows significant increases in its radon content m the time of an earthquake occurrence [38,39] However, it is known that other environmental factors such as barometric pressure, temperature, rainfall.

Normally, in air applications, measured in atmospheres, pascal (Pa) or pounds per square inch (psi). Primary pollutants—Pollutants that are emitted directly into the atmosphere where they exert an adverse influence on human health of the environment.

An increase in barometric pressure compresses downward the soil air originally occupying the pores whilst a decrease in barometric pressure induces egress of soil air into the atmosphere. Turbulent wind blowing as gusts across the surface of soil produces slight but numerous changes in pressure and adds to the pumping effects of longer 5/5(6).

This book provides a broad and interdisciplinary view of the different processes, models, experimental methods, and applications associated with gas and vapor transport in porous media.

We hope that the reader develops an understanding of the many diverse topics and an appreciation for the important applications covered in this book. In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey collected data on total dissolved gas pressure, barometric pressure, water temperature, and dissolved oxygen pressure at 11 stations on the lower Columbia River from the John Day forebay (river mile ) to Wauna Mill (river mile ) from March to September.
