2014, Marine ChemistryCitation Excerpt :For the calibration of the RaDeCC efficiencies for the MnO2 cartridges, the absolute activity (dpm) per sample is needed. After the initial RaDeCC counting was completed, the cartridges were ashed at 820 °C followed by acid leaching using 8 N HNO3 and wet chemistry separation (Buesseler et al., 1992). Briefly a known amount of 230Th spike was added to each sample for estimating sample recoveries and the same chemical purification and alpha counting method for the particulate samples outlined above was followed.
