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.
Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

An investigation room to interrogate packages and baggage at airports, based on a neutron-induced gamma-ray method, was designed using the MCNP5 Monte Carlo radiation transport code. A pulsed neutron generator source of interval time responses 10 μs turned on and 100 μs turned off was used for the investigation. Gamma-ray emissions in the forward, scattering angle of 90 deg, and backward directions were detected in the two cases of neutron generator (turned on/turned off). The detected data revealed that gamma rays in the forward direction have a signal-to-background ratio higher than the other positions. In addition, thermal neutron capture detected in the turned-off interval showed larger numbers of good signal-to-background ratio than that in the turned-on interval. The results show that the detection of gamma rays induced with a pulsed neutron source can be applied as a basic technique in airports to identify smuggled illicit materials.
