ABSTRACT

There are presented results of periodic measurements of radioactive gas - radon content
in sea, river and drinking water in resort zone Ureki-Shekvetili at the Black Sea coast of
Georgia during the period from September, 2008 till October, 2009. It is shown, that the
level of radon content ranges in interval 0.12 – 0.44 Bq/L in sea water, 0.15 - 0.58 Bq/L
and 0.13 – 0.59 Bq/L in river water for river Natanebi and river Supsa, accordingly, 7.9
– 14.0 Bq/L and 1.19 – 4.35 Bq/L in drinking tap and artesian water, accordingly. There
were estimated radiological influence of the radon dissolved of water on health of
people; average values of committed effective dose and dose equivalent to stomach are
in limits from 0.0080 to 0.0285 and from 0.21 to 0.75 mSv·y-1, accordingly. All
obtained values of radon content and an estimation of radiological dozes in drinking
water are below recommended norms of maximum-permissible concentration given in
scientific literature.
