ABSTRACT
In the present work it was studied content of radioactive gas radon - Rn-222 in the number of sources of surface water of various type (spring, river, etc.) located in some settlements nearby to Tbilisi city (the capital of Georgia) in the territory of so-called Tbilisi artesian basin. Researches were carried out in during the annual period (January-December); samples for measurements in some settlements were selected monthly. Radon detector RAD7 was used for determination of radon content. It was established, that radon content in water considerably changes depending on the source location as well as on water type too. So, for example, radon content in various sources of spring water was in the limits from several units of Bq L-1 up to 100 Bq L-1 and more. Radon content in water of other types is much less. It was carried out systematization of sources by the groups of activity (seven groups of activity, from very low - less than 0.3 Bq L-1 up to ultrahigh - more than 100 Bq L-1). Possibility of influence on various factors on the radon content was analyzed, for example, features of soil-geological structure, features of water sampling, etc. Comparison with literary data has been carried out.
