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.

ARG-US Remote Monitoring Systems: Use Cases and Applications in Nuclear Facilities and During Transportation
As highlighted in the Spring 2024 issue of Radwaste Solutions, researchers at the Department of Energy’s Argonne National Laboratory are developing and deploying ARG-US—meaning “Watchful Guardian”—remote monitoring systems technologies to enhance the safety, security, and safeguards (3S) of packages of nuclear and other radioactive material during storage, transportation, and disposal.

This work deals with the evaluation of interaction cross sections, effective atomic number, and effective electron density at gamma photon energies, not available from standard radioisotopes. The Compton scattering technique is used to obtain the required gamma energies within a specific range of energies from 241.8 to 401.8 keV to perform the radiation measurements. Radiation interaction parameters of some inorganic compounds (high-Z rare-earth nitrate hexahydrate), namely, Lanthanum(III) nitrate hexahydrate [La(NO3)3.6H2O] and Samarium(III) nitrate hexahydrate [Sm(NO3)3.6H2O], soluble in low-Z organic solvent (acetone) are evaluated. Six scattering angles are chosen to obtain six (not available from standard radioisotopes) Compton scattered energies to perform narrow-beam transmission experiments. An NaI(Tl) scintillation detector is used to detect the transmitted flux from the different solutions in various proportions. Photon interaction parameters useful in vast basic and applied fields are evaluated. The present measured results, obtained from the Compton scattered technique, are found to be in good agreement with the computed values of radiation interaction parameters obtained from the WinXCom program. The present data on rare-earth solutions have definite scientific importance in nuclear and radiation physics and fill in the gap of nonavailability of such data for radiation workers at these specific energies.
