A review is given on the radon survey in the Slovenian karst caves, those open for tourists and those for cavers and spele­ologists only. Radon concentrations differed markedly from cave to cave, as well as from point to point in the same cave. In addition to radon, in the Postojna Cave also radon decay prod­ucts (RnDP), equilibrium factor between radon and RnDP, and the unattached fraction of RnDP have been monitored. Based on highradon levels, permanent radon monitoring was intro­duced in Postojna Cave and time spent by workers in the cave limited in order to keep their exposure to radon acceptably low.
