| Zusammenfassung |
| The Ravne tectonic fault in north-west (NW) Slovenia is one of the faults in
this region, responsible for the elevated seismic activity at the
Italian-Slovene border. Five measurement profiles were fixed in the vicinity
of the Ravne fault, four of them were perpendicular and one parallel to the
fault. At 18 points along these profiles the following measurements have
been carried out: radon activity concentration in soil gas, radon exhalation
rate from ground, soil permeability and gamma dose rate. The radon
measurements were carried out using the AlphaGuard equipment, and GammaTracer
was applied for gamma dose rate measurements. The ranges of the obtained
results are as follows: 0.9–32.9 kBq m−3 for radon concentration
(CRn), 1.1–41.9 mBq m−2 s−1 for radon exhalation rate
(ERn), 0.5–7.4×10-13 m2 for soil permeability,
and 86–138 nSv h−1 for gamma dose rate. The concentrations of
222Rn in soil gas were found to be lower than the average for Slovenia.
Because the deformation zones differ not only in the direction perpendicular
to the fault but also along it, the behaviour of either CRn or
ERn at different profiles differ markedly. The study is planned to
be continued with measurements being carried out at a number of additional
points. |
