摘要：

Radon concentration measurements were carried out using solid-state nuclear track-etch detectors (RSKS) type CR-39 in Polovragi and Muierilor limestone caves from Easthern Carphatian (Romania). Two campaigns for measurements were. performed in each cave (winter and spring seasons). The time-periods for which measurements were performed provide reliable data for estimating the dose exposure to the radon for tourist guides. Higher radon levels were measured in Polovragi cave in the spring season, 3331 Bq m(-3) being the highest value. In this cave the gradual accumulation of radon further and deeper into the cave in the absence of air movement inside the cave was demonstrated. Muierilor cave is characterized by slightly variation of radon concentration through the caves caused probably by the high air movement inside the cave. Some anomalies were recorded in several measurement points probably due to the local conditions.
