Automation of irradiated bismuth target dissolution and astatine recovery from nitric acid media has been achieved at Texas A&M University. This process can be controlled remotely; it does not require any chemical treatment or evaporation solution prior to the separation above-mentioned elements on an extraction chromatography column, making final product ready within 20 min. The accompanying r...

The newly measured ionization potential of atomic astatine is discussed and compared with that the recently determined value for polonium other halogens. Regularities in these values are applied to understanding energetics diatomic Some surprises remain.

ConspectusAstatine (At) is the rarest on Earth of all naturally occurring elements, situated below iodine in periodic table. While only short-lived isotopes (t1/2 ? 8.1 h) are known, 211At object growing attention due to its emission high-energy alpha particles. Such radiation highly efficient eradicate disseminated tumors, provided that radionuclide attached a cancer-targeting molecule. The in...
