The total efficiency and the minimum detectable activity were calculated to be 95% and 30 mBq, respectively, for a liter sample and 1000-minute measuring time. The method has been applied successfully for the determination of alpha-radioactivity in seawater from five different coastal areas in Cyprus. The average alpha-radioactivity and uranium concentration were found to be 124±8 mBq·1-1 and 3.2±0.2 μg·1-1, respectively.||URI:||http://ktisis.cut.ac.cy/handle/10488/11049||ISSN:||1588-2780||Rights:||© 2006 Akadémiai Kiadó.||Type:||Article|
