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.

Heating effects of translated field-reversed configuration plasma into a chamber where neutral particles are filled is investigated by numerical calculation. Here, neutral particle species of deuterium, helium, and argon atoms are considered and translation speed is over 100 km/s. The calculation results show helium atoms penetrate most deeply into the plasma. Although argon ions that have the largest mass can transfer most their translation energy relative to the FRC plasma, energy recovery rate is found to be low due to the orbit loss.
