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.
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.

Hydrogen plasma-driven permeation (PDP) experiments have been conducted, using a steady state linear plasma device for the membranes made of reduced activation ferritic steel (F82H) and stainless steel (SUS304). The steady state PDP ratios have been measured to be of the orders of 10-3 and 10-4 at ~220 °C for 1 mm thick F82H and SUS304 membranes, respectively. For F82H, the steady state PDP flux ratio has been found to be inversely proportional to membrane thickness at ~220 °C, indicating that permeation is diffusion-limited. From the temperature dependent PDP data for F82H an activation energy has been evaluated to be ~0.5 eV.
