ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

We have successfully sputter coated sub-micron layers of quartz onto plasma polymer shells. An agitation mechanism based on an electromagnetic shaker was used. Coatings as thin as 0.4 μm that retain their integrity have been deposited. These coatings have permeation rates against helium at room temperature that are similar to those of thermal quartz. However, the permeation rates to D2 and argon of coatings thinner than ≈ 2 μm are higher than expected. In contrast, coatings thicker than 2 μm had D2 half-lives that were long enough to make them useful as a permeation barrier. Diffusion along grain boundaries or through pinholes is a likely reason for the high permeation rates through the thinner coatings. Because plasma polymer becomes thermally unstable near 300°C, these composite shells have to be filled at a maximum temperature of 250°C.
