Analysis of uranium radium in environmental samples

1995-12-1  The high sensitivity and element specificity of ICP-MS has been instrumental in the development of methods for the analysis of long lived radionuclides including Uranium and Radium. Traditional sample preparation was used and the resulting preconcentrated sample was analyzed quantitatively using ICP-MS equipped with an Ultrasonic nebulizer.
