Radon in the spas of Croatia

Radon concentrations in air and geothermal water of the spa pools in Croatia were measured and the average values of 40.3 Bq/m^3 and 4.5 kBq/m^3 were obtained, respectively. Great difference between radon concentrations in pool and spring water was considered as result of the mixing normal and geothermal water in the pool as well as the radon decay. Estimation of the effective dose equivalent, received by the personnel in the Stubica spa, gave the value of 0.7 mSv/y. At the same location, the transfer factor of the radon for air and thermal water in the pool was calculated, and the value of 4.9x10^-3 was obtained.
