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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

In vivo measurements are usually carried out under the hypothesis of a known activity distribution inside the body. The measurements and the interpretation of in vivo measurements performed with the minimum hypothesis about the activity distribution are presented and discussed. Measurements have been performed with a devoted four-germanium-detector system on a male subject presenting a 30-yr-old wound contamination by americium and plutonium isotopes. The measurements have been processed after the construction of voxelized phantoms of the measured body parts and Monte Carlo (MC) calculations of organ- and detector-specific counting efficiencies. The phantom construction and MC calculations were assisted by the OEDIPE software, and the reliability of the modeling has been controlled by a comparison of the measured and simulated efficiencies for point-source measurements and for the measurement of a Spitz anthropomorphic knee phantom. Mainly based on measurements at the knee level, the 241Am specific bone activity was (0.27 ± 23%) Bq/g. Using measurements at the thorax level, no activity could be detected in the lungs; the liver activity was between 410 and 460 Bq. The activity of the axillary, thoracic airways and trunk lymph nodes depends on the retained hypothesis, but a reasonable assessment for the axillary lymph nodes is between 100 and 350 Bq.
