Abstract
Radon alpha activities were evaluated in different
places of a quaternary cave (endokarstic formation), by the Solid State
Nuclear Track Detectors (SSNTD) technique. The maximum activity was detected
in the place more moved back of the studied cave. The ventilation phenomenon
has been investigated. The radon alpha activity and uranium content
according to the growth of stalagmite samples from the cave were evaluated.
A positive correlation has been shown between the uranium distribution
(radon) and the stratigraphic order of the stalagmite samples.
