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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

Resonance integral calculations are done for 232Th infinite dilute, 232Th metal rod, and 232Th02 rod systems. Doppler effect calculations are performed for 232 Th02 rod systems for temperatures up to 2000°K. The resolved resonance integral for rod systems at each temperature is evaluated by Monte Carlo calculations and the resonance overlap effect between the two resonances of Th at 21.78 and 23.45 eV is taken into account. The unresolved s- and p-wave contributions were computed by standard methods. The data describing the resolved resonance parameters up to 3 keV (гγ = 25.9 meV) recommended in BNL-325 (Supplement No. 2, 1965) are used in these calculations. The p-wave strength function in the unresolved energy range is taken to be 1.83 x 10 -4 (eV)-1/2. The calculated resonance integrals and Doppler coefficients are compared with measurements and they are found to be in excellent agreement with each other.
