Control of Radon Flux of an Inactive Uranium Mill Facility in Spain

open access: yesAtmosphere, 2023
As part of a contract with ENRESA (National Radioactive Waste Company S.A. is a Spanish public company responsible for the management of radioactive waste), after the closure of the uranium mill factory in Andújar, Spain, continuous measurements of the ...

First Steps towards a National Approach for Radon Survey in Romanian Schools

open access: yesAtmosphere, 2021
Schools are a category of public buildings with a high radon exposure risk, due to their high occupancy factor. In Romania, the elaboration of a methodology for radon measurements in schools is a necessity imposed both by the European legislation and by ...

Use of radon barriers to reach an acceptable radon level [PDF]

open access: yesE3S Web of Conferences, 2020
A method is presented for theoretically estimating the necessary airtightness of a radon barrier. Radon barriers are used to balance the indoor radon concentration.

Overview of Radon Flux Characteristics, Measurements, Models and Its Potential Use for the Estimation of Radon Priority Areas

open access: yesAtmosphere, 2022
Radon flux measurements provide information about how much radon rises from the ground toward the atmosphere, thus, they could serve as good predictors of indoor radon concentrations.

Blood flow but not cannula positioning influences the efficacy of Veno-Venous ECMO therapy

open access: yesScientific Reports, 2022
Despite being vital in treating intensive-care patients with lung failure, especially COVID-19 patients, Veno-Venous Extra-Corporeal Membrane Oxygenation does not exploit its full potential, leaving ample room for improvement. The objective of this study

Elementary vectors and conformal sums in polyhedral geometry and their relevance for metabolic pathway analysis

open access: yesFrontiers in Genetics, 2016
A fundamental result in metabolic pathway analysis statesthat every flux mode can be decomposed into a sum of elementary modes.However, only a decomposition without cancelations is biochemically meaningful,since a reversible reaction cannot have ...

Concentrations of indoor and soil radon in Lithuania/Radonas grunto ore ir pataleose Lietuvoje

open access: yesJournal of Civil Engineering and Management, 1998
Uranium and its daughters including Ra-226 are naturally present in the Earth's crust and other environmental bodies. During decay of Ra-226 radioactive noble gas radon is produced.

Geologic, seasonal, and atmospheric predictors of indoor home radon values

open access: yesEnvironmental Research: Health, 2023
Exposure to tobacco smoke and radon cause lung cancer. Radioactive decay of naturally occurring uranium in bedrock produces radon. Seasonality, bedrock type, age of home, and topography have been associated with indoor radon, but the research is mixed ...
