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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

A theoretical and experimental study of an aerosol particle charging apparatus that utilizes a 407-MBq (11-mCi) 90Sr-90Y beta source and electric and magnetic fields has been performed. Fluid models of electron trajectories in the presence of the magnetic field, ion generation due to electron energy deposition, and particle charge acquisition due to ion transport are developed and applied to the experimental apparatus. Calculated average axial ion generation rates on the order of 1014/m3· s are confirmed by experimental measurements, and calculated radial profiles are in good agreement with experiments. Calculated and experimental charging rates agree within 30% for 50- to 100-μm-diam glass spheres in an electric field of 100 kV/m and a magnetic field of 0.141 T. It is found that both the magnitude and spatial distribution of the ion generation rate play important roles in determining the rate of charge acquisition by an aerosol particle in a partially ionized gas subjected to an external electric field.
