The target for the production of68Geconsists of a disc of gallium suboxide, Ga2O, with a 19 mm diameter. The suboxide was primarily prepared by repeatedly mixing metallic Ga and Ga2O3at 700 °C. The target (2.4 g) was quite stable under a long-time i

Image degradation during single photon emission computed tomography (SPECT) due to attenuation and Compton scatter of photons can cause clinical image artifacts and will also result in inaccurate quantitative data. Therefore attenuation correction me

A method is described for the highly accurate determination of trace amounts of uranium in standard reference materials. The uranium is separated from the bulk elements by anion-exchange chromatography, eluting most elements with 6 M hydrochloric aci

It is shown that substantial amounts of uranium can be lost at the interface between eluting agents when two different groups of interfering elements are eluted successively from a single anion exchange column with sulfuric acid or ammonium sulfate f
