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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

We have added a source definition component to the Moritz geometry editing and display program. Gamma line emission can be imported from a library based on the Brookhaven National Laboratory Nuclear Data Center. The user can select one or more isotopes from a tree view list. The abundances can be corrected for radioactive decay between two times. The line emission is then converted to MCNP SDEF format. Tabulated data, such as an X-ray tube spectrum, can be read and converted to MCNP format. Interactive tools are available for defining source volumes, direction, cone source opening angle, and bias direction; these items can be shown together with the geometry. All source definition items can be entered exactly in dialog fields. Source definitions can be read from existing input files. The tools will expedite and verify source definition and ensure accuracy and do not require knowledge of the MCNP SDEF syntax.
