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.
