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 albedo component of gamma rays passing through a straight cylindrical lead duct has been investigated experimentally for reactor leakage gamma rays impinging on the duct mouth at various angles of 0 through 90°. The distribution of the albedo component along the duct axis may be expressed in the form F(α)·(Z/a)-3 within the range of Z/a investigated. The contributions from multiple-reflection components to total dose have also been inferred. Also obtained were the radial distributions in both horizontal and vertical directions within and behind the duct., For a duct with one bend of 90°, the gamma-ray dose contributions arising from scattering areas located in both the first leg and the second leg have been determined separately for the incident beam angle of 0° with respect to the axis of the first leg.
