An alpha fast-slow coincidence counter has been designed and manufactured for measuring the low alpha activities of 223Ra and 224Ra in the seawater. In this work, Radium from the seawater was absorbed onto a column of MnO2 coated fiber (Mn fiber). | Development of an alpha fast-slow coincidence counter for analysis of 223Ra and 224Ra in seawater
