Study On Analytical Methods Of Tellurium Content In Natriiodide (Na131I) Radiopharmaceutical Solution Produced In The Dalat Nuclear Reactor

This report describes the practical methods for analyzing of Tellurium content in Na131I solution produced at the Dalat Nuclear Research Institute. We studied analytical methods to control Tellurium content in final Na131I solution product used in medical purposes by three methods such as: spot test, gamma spectrometric and spectrophotometric methods. These investigation results are shown that the spot test method is suitable for controlling Tellurium trace in the final product. This spot test can be determinate Tellurium trace less than 10 ppm and are used to quality control of Na131I solution using in medical application. (author)
