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.

The D&D of SM-1A
With the recent mobilization at the site of the former SM-1A nuclear power plant at Fort Greely, Alaska, the Radiological Health Physics Regional Center of Expertise, located at the U.S. Army Corps of Engineers’ Baltimore District, began its work toward the decommissioning and dismantlement of its third nuclear power plant, this time located just 175 miles south of the Arctic Circle.

Spectra of backscattered radiation from semi-infinite slabs of paraffin, aluminum, iron, tin, and lead were measured by means of a scintillation spectrometer, as a function of the measuring angle θ, which is the angle between the normal to the plane face of the slabs and the detector axis. The point gamma sources of Co60 and Cs137 were placed in close contact with the scattering slabs. By using this geometry the measurement was performed without perturbing effects produced by detector or source collimating shields. The energy and number albedos, the angular distributions of scattered energy and number of photons, and the energy distributions are given for each combination of gamma source and scatterer.
