Abstract
Prodn. and quality assurance methods for short-lived and high specific activity radionuclides were developed. Irradiations were performed with the Scanditronix MC40 cyclotron (K = 38; p, d, He-4 and He-3). In order to optimize the irradn. conditions for Pt radiotracer prodn., both thin-and thick-target excitation functions of natOs(α,xn) nuclear reactions were measured. A selective radiochem. sepn. to obtain Pt radiotracers in no-carrier-added form, was developed. Specific activity and chem. purity of the radiotracers were detd. by n activation anal. and at. absorption spectrometry. An isotopic diln. factor of ≈50 was achieved.
