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.

Matthew Denman: On Probabilistic Risk Assessment
Probabilistic risk assessment is a systematic methodology for evaluating risks associated with a complex engineered technology such as nuclear energy. PRA risk is defined in terms of possible detrimental outcomes of an activity or action, and as such, risk is characterized by three quantities: what can go wrong, the likelihood of the problem, and the resulting consequences of the problem.
Matthew Denman is principal engineer for reliability engineering at Kairos Power and the chair of the American Nuclear Society and American Society of Mechanical Engineers Joint Committee on Nuclear Risk Management’s Subcommittee of Standards Development. As a college student at the University of Florida, Denman took a course on PRA but didn’t enjoy it, because he did not see its connection to the nuclear power industry. Later, during his Ph.D. study at the Massachusetts Institute of Technology, his advisor was Neil Todreas, a well-known thermal hydraulics expert. Todreas was working on a project with George Apostolakis, who would leave MIT to become a commissioner of the Nuclear Regulatory Commission. The project, “Risk Informing the Design of the Sodium-Cooled Fast Reactor,” was a multi-university effort funded through a Department of Energy Nuclear Energy Research Initiative (NERI) grant. Todreas and Apostolakis were joined in this project by a who’s who of nuclear academia, including Andy Kadak (MIT, ANS past president [1999–2000]), Mike Driscoll (MIT), Mike Golay (MIT), Mike Lineberry (Idaho State University, former ANS treasurer), Rich Denning (Ohio State University), and Tunc Aldemir (Ohio State University).
Power up the learning in your classroom with digital lesson plans, project starters, career resources, and more that introduce students to nuclear processes and the surprising ways they benefit society!
Explore the vast world of nuclear science with your students to uncover the diverse applications of this field and debunk some common misconceptions about nuclear. From fission, to fusion, to building their own atoms, students will learn nuclear processes and applications while developing key STEM skills.

Watch as Mary Lou Dunzik-Gougar, Immediate Past President of the American Nuclear Society and Associate Professor of Nuclear Engineering at Idaho State University, demonstrates ways to make this digital lesson bundle even more tangible and engaging for student scientists!
Lesson Bundle | 45 Minutes
In this digital lesson bundle, students will investigate the various types of radiation and the role that each plays in our lives. Students will discover how wave and particle radiation differ and what ionizing radiation is. They will learn about the radioactive decay of isotopes and use this information to balance nuclear decay equations.

Educator Lesson Plan | 45 Minutes
In this activity, students will summarize the unique characteristics of radiation and how it is used to treat cancer through a Think-Pair-Share activity.
In this activity, students will be introduced to the concepts of mass defect and nuclear binding energy. They will explore the idea of nuclear binding energies in the context of fusion as they calculate the amount of energy released in a fusion reaction using Einstein’s published E=mc2 equation.
Students will learn to use the periodic table as a tool to predict a nuclide’s properties. After a quick vocabulary refresher, students will engage in an interactive “Heads Up” game, working in groups to use the periodic table to correctly guess the term shown on a card.
Students first will watch a video explaining fission and fusion. Then, students will apply their knowledge of fission and fusion as they engage in a kinesthetic “Four Corners” activity, voting with their feet as they compare fission and fusion.
How does radiocarbon dating help detect art forgeries?
In this activity, students will investigate radioactive decay, half-life, and the process of radiocarbon dating.

How are radioactive isotopes used in nuclear batteries?
Students will compare and contrast different types of nuclear processes and design a future prototype for a small-scale nuclear battery that will address one of three design problems.
How can radiation solve problems and benefit humans?
In this lesson, students will be introduced to how radiation, such as gamma radiation, can be used to help solve problems by examining the quest to eradicate Aedes mosquitoes using the Sterile Insect Technique: (SIT).
