Determination of Specific Activity and Tellurium (IV) Concentration in Non-Carrier Added Iodine-124 Solutions, Via UV-Vis Spectroscopy

In this work, two fast and highly sensitive analytical methods, based on UV-VIS spectroscopy, were adapted for its use on the determination of specific activity (SA) and Tellurium (IV) concentration, in 124I- solutions produced by the 124Te(p,n)124I reaction. The solutions analyzed showed high specific activity (209 - 216 Ci/mg) and Te(IV) contents below the regulatory acceptable limit (1 ppm).
