The origin and detection of spike-like anomalies in soil gas radon time series
radon detection spike-like anomaly
2017/4/12
Desorption of radon is of short duration but longer than telluric noises and is usually accomplished in less than one
minute based on our binary event counting with a 16 second interval. Adapting an ...
A possible link between radon anomaly and earthquake
soil gas lineaments meteorological parameters
2017/4/12
Radon in soil gas had been measured at 39 locations, distributed along three prominent lineaments in the Guwahati
city, Assam, India; using solid state nuclear track detectors. The most suitable site...
Radon activity concentrations measurements in some Jurassic caves of Poland are presented. The aim is to estimate
the radiation doses to casual visitors, cavers and guides in show caves. Radon levels...
Seasonal variation of radon concentrations in atmospheric air in the Nowa Ruda area (Sudety Mountains) of southwest Poland
utdoor radon seasonal and spatial variations
2017/4/12
Atmospheric radon concentrations were monitored from autumn 2004 to winter 2007 in an abandoned coal mining
area of SW Poland that contained various bedrock uranium contents, ranging from 1 to 8 ppm....
Continuous radon monitoring in the Jowshan hot spring as an earthquake precursor, SE Iran
earthquake precursor Jowshan hot spring continuous monitoring
2017/4/12
In this paper, we present the results of the first experience for spring water 222Rn concentration continuous monitoring
in Jowshan hot spring, SE Iran, from December 2007 to July 2008. This hot spri...
Periodic and transient radon variations at the Tiberias hot spring, Israel during 2000–2005
radon time-series analysis wavelet Roman spring
2017/4/12
Radon has continuously been monitored at the Roman spring of Tiberias, Israel since 2000 in the frame of an earthquake
research project. However, there was no apparent earthquake related radon anomal...
Soil radon flux and concentrations in hydrothermal area of the Tatun Volcano Group, Northern Taiwan
soil radon hydrothermal area Tatun Volcano Group volcanic gas
2017/4/12
Rn (radon) is the major radioactive gas in volcanic area. The study of radon concentration variations in volcanic
areas has been considered as a useful tool to investigate the volcanic activity in on...
Radon exhalation from the Upper Silesian coal ashes
radon exhalation coal ashes emanation coefficient
2017/4/12
The radon exhalation has been measured for samples of coal ashes by the can technique. In this technique, the ratio of
the radon content in the air inside the can and the total radium content of the ...
Radon-Nikodým compact spaces of low weight and Banach spaces
Radon-Nikod´ ym compact quasi Radon-Nikod´ ym compact
2011/2/28
We prove that a continuous image of a Radon-Nikod´ym compact of weight less than b is Radon-Nikod´ym compact. As a Banach space counter-part, subspaces of Asplund generated Banach spaces o...
The purpose of this announcement is to describe a development given in a series of forthcoming
papers by the authors that concern operators of the form f 7→ (x) Z f ( t (x))K (t) dt.
Residual d-bar-cohomology and the complex Radon transform on subvarieties of CPn
Residual d-bar-cohomology complex Radon transform subvarieties of CPn
2011/2/24
We show that the complex Radon transform realizes an isomorphism between the space of residual
¯ @-cohomologies of a locally complete intersection subvariety in a linearly concave domain of CPn ...
A remark on primitive cycles and the Radon transform
primitive cycles the Radon transform
2010/11/17
We show that the use of Brylinski's Radon transform elucidates some points of the Green-Griffiths approach to the Hodge conjecture.

A map of radon flux at the Australian land surface
A map of radon flux the Australian land surface
2010/10/11
A time-dependent map of radon-222 flux density at the Australian land surface has been constructed with a spatial resolution of 0.05° and temporal resolution of one month. Radon flux density was calcu...
We give a survey of basic results on the cut norm and cut metric for graphons (and sometimes more general kernels), with emphasis on the equivalence problem. The main results are not new, but we add v...
