Abstract
Owing to its exceptional radiotoxicity 226Ra in drinking water may directly affect human health. Its presence was investigated in several categories of drinking water in Croatia: well water, tap water from several municipal water supply systems and bottled mineral water. The method of 226Ra determination was alpha-spectrometric measurement after radiochemical separation. The 226Ra content in all investigated categories of waters are below the legislative level permissible for human health.Zbog svoje izuzetne radiotoksičnosti, 226Ra u pitkoj vodi može izravno utjecati na ljudsko zdravlje. U radu je opisano istraživanje specifične aktivnosti 226Ra u pitkoj vodi Hrvatske, i to: u uzorcima bunarskih voda, uzorcima vodovodnih voda u nekoliko gradova Hrvatske i u mineralnim vodama. 226Ra je određen alfa-spektrometrijskim mjerenjem nakon radiokemijske separacije. Istraživanje je pokazalo da je količina 226Ra u svim ispitivanim kategorijama voda ispod razine koju zakonska regulative smatra tolerantnom po zdravlje čovjeka
