| Abstract: | Water 226Ra concentration in springs was measured in regions with high indoor radon: Ural, North Caucasus (Russia), Niska Banja (Serbia), Piestany (Slovakia), and Issyk-Kul (Kyrgyzstan). This paper presents the results for 226Ra concentration above 0.03 Bq l–1. Radium in water could indicate indoor radon problem in the region and water investigation is useful at the initial stage of radon survey. Even low 226Ra concentration in water (0.1–0.6 Bq l–1) caused high 226Ra activity in travertine (up to 1500 Bq kg?1), which resulted in indoor radon concentration above 2000 Bq m?3 (Niska Banja). |
