Kernel-based Image Reconstruction from Scattered Radon Data [PDF]

open access: yes, 2016
Computerized tomography requires suitable numerical methods for the approximation of a bivariate function f from a finite set of discrete Radon data, each of whose data samples represents one line integral of f .

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 ...

Radiation protection considerations on radon and building materials radioactivity in Near Zero Energy Buildings [PDF]

open access: yes, 2017
Recent updates of the E.U. Basic Safety Standards, stated in the Council Directive 2013/59/EURATOM, are focusing on risks related to radon gas concentration inside dwellings and working places, as well as radioactivity of building materials.

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.

Scale-discretised ridgelet transform on the sphere [PDF]

open access: yes, 2019
We revisit the spherical Radon transform, also called the Funk-Radon transform, viewing it as an axisymmetric convolution on the sphere. Viewing the spherical Radon transform in this manner leads to a straightforward derivation of its spherical harmonic ...

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 ...

The Laboratory of Natural Radiation (LNR) – a place to test radon instruments under variable conditions of radon concentration and climatic variables

open access: yesNukleonika, 2016
The publication of the new European Union Basic Safety Standards represents a remarkable milestone in the field of radiological protection in terms of adding radon exposure to this framework.

The imprint of thermally induced devolatilization phenomena on radon signal. Implications for the geochemical survey in volcanic areas [PDF]

open access: yes, 2017
Thermal gradients due to magma dynamics in active volcanic areas may affect the emanating power of the substrate and the background level of radon signal.

Radon hazard vs. radon risk - On the effectiveness of radon priority areas

open access: yesJournal of Environmental Radioactivity, 2022
The detrimental health effects of radon have been acknowledged by national and international legislation such as the European Union Basic Safety Standards (EURATOM-BSS Article 103/3) which requires member states to delineate radon priority areas.

Soil radium, soil gas radon and indoor radon empirical relationships to assist in post-closure impact assessment related to near-surface radioactive waste disposal [PDF]

open access: yes, 2009
Least squares (LS), Theil’s (TS) and weighted total least squares (WTLS) regression analysis methods are used to develop empirical relationships between radium in the ground, radon in soil and radon in dwellings to assist in the post-closure assessment ...
