Measured value of radon content was 200÷257 Bq/m3 and the summary alpha radioactivity in cave air was in the range of 600÷771Bq/m3. Measured light ions concentration was 18200÷22250 cm−3 for positive and 24000÷24280 cm−3 for negative ions. Based on these measurements it was concluded that microclimatic, bioclimatic and ionizing conditions in the cave are appropriate for therapeutic purposes.Avtandil Amiranashvili, Victor Chikhladze, Kukuri Tsikarishvili, Khatuna Tsiklauri On the Restoration of the Ionization Properties of “Tetra” Cave (Tskaltubo, Georgia) Scientific Conference “Actual Problems of Geography”. 5–6 November 2019, Tbilisi, Georgia
