| Zusammenfassung |
| The 222Rn activity concentration in ground water from four boreholes was
investigated from January 2006 to June 2008. The boreholes are situated in
the region of the Astronomical and Geophysical Observatory in Modra-Piesok
(Little Carpathians Mts., 40 km NW from Bratislava, Slovakia). Three
boreholes have been drilled in Lower Triassic quartzite. Another borehole has
been drilled in granodiorite of the Modra massif in which the quartzite is
folded. Temporal and spatial differences in radon concentration were
observed. Significant short-term variations were noticed in all boreholes.
Precipitation caused the changes of water level and strongly affected the
values of 222Rn activity concentration in less deep boreholes. The
measured activities in boreholes ranged approximately over 1–240 kBq/m3. |
