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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

SNAP-11 is an isotope-fueled thermoelectric generator, fueled with 7.5 g of 242Cm, which was obtained from 241Am irradiated to ∼1.2 × 1021 n/cm2. The irradiated material was dissolved in hydrochloric acid 15 to 30 days after discharge from the reactor and processed through two cycles of solvent extraction to remove ionic and radioactive contaminants. The curium and americium were converted to the sesquioxide, pelletized, and encapsulated into the isotopic heat source. The heat source was installed in a thermoelectric converter package to complete the SNAP-11 system, which was then tested for 90 days in a lunar environment simulator at a pressure of 10−7 Torr and temperatures from −235 to +235°F. It successfully met all performance specifications.
