“…An experiment on radon level measurement in well water was conducted by Yalim et al (2007) at the Aksehir fault zone, Afyonkarahisar. They observed the radon level at the fault region where several high magnitude seismic activities have occurred, though they did not infer about correlation between seismic activity and radon concentration.…”

“…The possibility of a correlation between radon concentrations in waters, rocks and soil and future earthquakes have been reported in several publications over the last few decades (e.g. Scholtz et al 1973;Rikitake 1976;Ioannides et al 2003, Crockett et al 2006Yalim et al 2007;Ondoh 2009). Attempts to find a connection between the concentration levels of released radon and helium prior and during seismic events have been made (Nikolin et al 1972, Monnin & Seidel 1997Virk & Walia 2001).…”

Outbursts (releases of gas and coal from exposed coal face) are dangerous events in coal mines, potentially leading to damage in the galleries and casualties among miners. For that reason, monitoring of this hazard is very important in collieries with seams prone to outbursts. Current hazard indicators are not sufficient for the proper prediction of geodynamic events and any effort to find a new and better method of monitoring is thus desirable. During the 1980s and 1990s, attempts were undertaken to apply specific radiometric methods to support the prediction of outbursts in collieries in the Lower Silesian Coal Basin (LSCB) in south-western Poland. This idea was developed as an analogy to the study of radon changes in groundwater prior to earthquakes. This study investigates the hypothesis of possible variations of radon emanation from coal seams prior to outbursts. Techniques and a methodology of radon observation in gas samples from strata were developed and applied. It has been stated that there is a degree of correlation between the temporal and spatial variations of radon level and the hazard level of an outburst. In the 1990s, all collieries in LSCB were abandoned and further investigations were thus stopped. In the last few years, the occurrences of outbursts were noticed in the collieries of Upper Silesian Coal Basin. For that reason, we initiated the monitoring of radon concentration as sampled from headings in dangerous coal seams. The purpose of the research is an attempt to introduce a new parameter, 'the radon indicator of outburst hazard', which could be used to support other routinely applied techniques of outburst prediction. This study provides some results from previous investigations performed in the collieries of the LSCB, as background and calibration to the preliminary results of the new research, performed in one of the coal mines in Upper Silesia region.

Background: It is considered that if radon gas is inhaled and ingested, it is the primary health risks for lung and stomach cancers. This paper presents the measurement results of radon ac vity concentra ons both residen al tap water and dam water for Kastamonu city Centre-Turkey. Materials and Methods: The radon ac vity concentra ons of water samples collected from 60 tap waters at four loca ons and 12 dam water of study area were determined. Radon concentra ons were measured using the professional radon monitor AlphaGUARD PQ2000 PRO (Genitron Instruments). , respec vely. The annual effec ve doses were calculated for the inhala on of radon released to air when water is used and the inges on of drinking water. The mean values for inhala on and inges on were found to be 0.1266 μSv y -1 and 0.0105 μSv y -1 , respec vely. For the radon exposure from inges on, the annual effec ve doses were calculated for infants, children, and adults, separately. Conclusion: When the results compared with the interna onally recommended safe limits, the tap waters of Kastamonu city Centre is safe for drinking purposes in terms of radon ac vity concentra ons.
