Gas radon emission related to geodynamic activity on Mt. Etna
radon geodynamical precursor Mt. Etna
2015/9/10
We report preliminary observations on possible correlations between anomalies of subsoil radon concentration
and geodynamical events on Mt. Etna. In recent years several studies have been carried out...
Radon, water chemistry and pollution check by volatile organic compounds in springs around Popocatepetl volcano, Mexic
soil radon water chemistry volcanic activity
2015/9/10
Popocatepetl volcano is a high-risk active volcano in Central Mexico where the highest population density in the country
is settled. Radon in the soil and groundwater together with water chemistry fr...
Radon data processing and outputs for the needs of the State Office for Nuclear Safety (according to the Czech Radon Programme)
radon-indoor-bedrock relationship radon mapping
2015/9/10
Much of the population living in the Czech Republic is exposed to radiation from natural sources, especially to the
radon effect. The aim of geological research defined by the State Office for Nuclea...
Distribution of radon activity in the atmosphere above Wzgórza Niemczansko-Strzelinskie (South-WestPoland) and its dependence on uranium and thorium content in the underlying rock and indirect ground basement
radon atmosphere uranium thorium rock
2015/9/10
Radon activity in the atmosphere and its behavior in the environment have been investigated using LR-115 nuclear
track detector. The complex geological structure of Wzgórza Niemczansko-Strzelinskie (...
Radon and thoron daughter activities in the environment of the King George Island (West Antarctica)
Antarctica radon uranium thorium spectrometry
2015/9/10
Results of 253 gamma spectrometric analyses of radon daughters in soil and bedrocks of the King George Island
(West Antarctica) are presented. Measured values range from 0.1 to 58.4 Bq/kg, and from 4...
Water chemistry and soil radon survey at the Poas volcano (Costa Rica)
Poas volcano geochemistry radon precursor
2015/9/10
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry
from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a fu...
Indoor and soil radon measurements in the Hyblean Foreland (South-East Sicily)
radon uranium indoor air soil gas Hyblean Foreland
2015/9/2
Indoor radon behavior in two sites of SE Sicily was studied as a function of the soil radon concentration. The
chosen locations were Ragusa and Modica towns, placed in the Hyblean Plateau (northern m...
The nexus of soil radon and hydrogen dynamics and seismicity of the northern flank of the Kuril-Kamchatka subduction zone
radon hydrogen seismicity geodeformation wave earthquake
2015/9/2
The comparison of kinematics and dynamic parameters of radon and molecular hydrogen concentration in subsoil
air on the stations network at the Petropavlovsk-Kamchatsky geodynamic proving ground with...
Radon and its decay product activities in the magmatic area and the adjacent volcano-sedimentary Intrasudetic Basin
radon uranium Sudetes mining
2015/9/2
In the magmatic area of Sudetes covering the Karkonosze granite and adjacent volcano-sedimentary Intrasudetic
Basin a study of atmospheric radon activity was performed by means of SSNTD Kodak LR-115....
Experimental studies of anomalous radon activity in the Tlamacas Mountain, Popocatepetl Volcano area, México: new tools to study lithosphere-atmosphere coupling for forecasting volcanic and seismic events
atmosphere electricity Litosphere-Atmosphere coupling
2015/8/24
This study presents and discusses the results of soil radon monitoring at three different volcano sites and one reference site, from December 2007 to January 2009. This relates to the activity of the ...
Fast Slant Stack: A notion of Radon Transform for Data in a Cartesian Grid which is Rapidly Computible, Algebraically Exact, Geometrically Faithful and Invertible
Radon Transform Projection-slice theorem Sinc-Interpolation,
2015/8/21
We define a notion of Radon Transform for data in an n by n grid. It is based on summation
along lines of absolute slope less than 1 (as a function either of x or of y), with values at non-Cart...
A simple statistical procedure for the analysis of radon anomalies associated with seismic activity
Radon emissions Seismic precursors Seismic activity
2015/8/18
This study presents an analysis of data from various radon anomalies that were compiled by Toutain and Baubron [1999], to investigate their relationships with the earthquake parameters of magnitude an...
A fast butterfly algorithm for generalized Radon transforms
fast butterfly algorithm generalized Radon transforms
2015/7/14
Generalized Radon transforms, such as the hyperbolic Radon transform, cannot be implemented as efficiently in the frequency domain as convolutions, thus limiting their use in seismic data processing. ...
