When it comes to the periodic table, the United States really blew its chance to make a name for itself. If you look over a map of all the elements named for cities, states, countries, and continents, ...

At any given point of time, there is only about 25 g of astatine that occurs naturally on our planet. If that doesn’t wow you, then it’ll help to nudge you along by mentioning that that is less than ...

IN 1940, we prepared the isotope of mass 211 of element 85 by bombarding bismuth with alpha particles accelerated in the 60-in. cyclotron of the Radiation Laboratory of the University of California 1.

Nuclear physicists at the ISOLDE radioactive-beam facility at CERN have for the first time measured key properties of astatine, the rarest element on Earth. This new study, with input from the ...

Cyclotron operator Randy Kemmler in the control room of the Crocker Nuclear Laboratory. UC Davis’ cyclotron will be used to produce the rare isotope astatine-211 for medical use under a ...

Researchers gain new insights into how the isotope astatine-211 interacts with resins commonly used to purify the isotope for therapeutic use Targeted Alpha Therapy (TAT) is one of the most powerful ...
