High specific activity 186Re and 188Re perrhenates to be used for biomolecule labeling

¹⁸⁶Re and ¹⁸⁸Re, two strong beta- and weak gamma-emitters having short half-lives, are intensely studied as promising radionuclides for radiotherapy. Their use for biomolecule labeling is mainly due to their similar behavior with ^99mTc. This paper presents the irradiation operations in a 14 MW Triga SSR Reactor, the chemical processing for obtaining a perrhenate solution of high activity and the final characterization of the products.
