Abstract
Analysis of radionuclide impurities in 166Ho-albumin microspheres prepared by activation with thermal neutrons of 165Ho preliminarily incorporated in the particle matrix was performed. The content of impurities in the final product was determined by γ-ray spectroscopy. With 166Ho-albumin microspheres as example, an algorithm was developed for evaluation of the radiochemical purity of the preparation. It was found that the radiochemical purity of the preparation, which is primarily determined by impurities of rare-earth elements, can be estimated from the content of 152mEu.
