An extraction method has been used to determine cerium144 in vegetation and soil. The principle advantages of the method are, (1) equilibration of cerium carrier and activity in the initial step of the procedure, (2) provision for the determination of strontium-90 and cesium-137 in vegetation and strontium-90 and normal cerium in soil. The results of measurements on fourteen wheat samples col l...

Following the March 2011 Fukushima disaster, large amounts of water contaminated with radionuclides, including Cesium-137, were released into the Pacific Ocean. With a half-life of 30.1 years, Cs-137 has the potential to travel large distances within the ocean. Using an ensemble of regional eddy-resolving simulations, this study investigates the long-term ventilation pathways of the leaked Cs-1...

Brachytherapy describes a process where radioactive sources are inserted directly into the target area of a patient to treat disease. Before they can be used for treatment, brachytherapy sources must be calibrated such that medical physicists know their exact air kerma strength a quantity given by manufacturers as a standard. Each individual source must be measured before use. Therefore, medica...
