“…The size of the target also needs to be sufficiently small to obtain the highest signal intensity for the lowest detection limit (DL). Although iron oxide targets have been extensively used for the determination of actinides, , our new target preparation method using a mixed titanium/iron oxide matrix showed very promising results for the detection of attogram levels of Cm isotopes by compact AMS . This new target preparation method has a few advantages over the traditional iron oxide methods, including: (1) high signal intensity using minimal amount of mixed oxides (<1 mg); (2) homogeneous distribution of the tracer and analyte nuclides in the target by co-precipitating actinides with mixed Ti/Fe hydroxide; (3) no high temperature baking step for conversion to the final oxide matrix, which significantly shortens the target preparation time and reduces the risk of cross-contamination.…”

“…Although AMS has been demonstrated for the precise and accurate determination of Pu at fg-levels in urine bioassay samples, the use of this technique for routine measurements has been limited by lack of availability and high operational costs of the complicated AMS system. In our recent study, the applicability of a compact AMS system at the Swiss Federal Institute of Technology (ETH) has been demonstrated for Pu urine bioassay at fg/L levels .…”

“…In the case of environmental samples, the uranium is solubilized by acid digestion, separated, and purified, following standard procedures common to other techniques such as alpha spectrometry. The purified solution containing 400 ng U was taken to dryness, the uranium redissolved in 10 mL of 3 M HNO 3 , and coprecipitated A description of the AMS system for heavy element analysis can be found in the literature [13,33]. In automatic operation, the system measures up to 5 different isotopes consecutively.…”
