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.
Radiation Protection & Shielding
The Radiation Protection and Shielding Division is developing and promoting radiation protection and shielding aspects of nuclear science and technology — including interaction of nuclear radiation with materials and biological systems, instruments and techniques for the measurement of nuclear radiation fields, and radiation shield design and evaluation.

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.

Supersonic Molecular Beam Injection (SMBI) experiments were performed at GAMMA 10 device under the collaboration with HELIOTRON Group of Kyoto University. In order to survey the effects of SMBI on the plasma behavior, we measured the plasma radiation by using the ultraviolet and visible (UV/V) spectroscopic system and study behavior of the neutral hydrogen and impurity ions emissions with using the collisional-radiative model (CR-model).With SMBI, the neutral hydrogen density calculated by the CR-model was about 20 times larger than that without SMBI. Impurity densities of oxygen ions also increased with SMBI.
