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.
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.
2021 Student Conference

ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

A formalism, based on particle, momentum, and energy balance constraints, for the interpretation of diffusive and nondiffusive transport from plasma edge measurements is presented and applied to interpret transport differences between low-mode and high-mode DIII-D [J. Luxon, Nucl. Fusion, Vol. 42, p. 614 (2002)] plasmas. The experimental values of basic transport properties (thermal diffusivities and momentum transport frequencies) inferred for H-mode and L-mode are compared with each other and with "classical" predictions. Once the basic transport mechanisms are ascertained by such comparison of theoretical predictions with experimental inference, the presented formalism will provide a first-principles predictive model for density, temperature, velocity, and pressure profiles in the edge pedestal.
