Results of ²²⁶Ra determination in thermal and mineral water springs, mostly spas and health resorts, in the Republic of Croatia are presented. These waters have been used on a large scale for medical and bathing purposes; for therapy, rehabilitation and recreation, while mineral waters from several locations are also used for drinking. The ²²⁶Ra content of thermal and mineral waters ranged from 0.07 to 4.40 Bq l⁻¹. In the spas in which waters were used both for bathing and drinking purposes, ²²⁶Ra activities in some springs were found to exceed the maximal permissible level of 1 Bq l⁻¹ for drinking water. On the assumption that a drinking cure contains 1 litre of mineral water daily for 1 week, the radium body burden originating from drinking this water would be on average 2.1 times higher than that originated from the consumption of 1 litre per day of tap water over 1 year.
