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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Uranium prices continue downward trend
Uranium prices have fallen to their lowest level in more than a month, to just under $79 per pound, on Friday, November 1, according to analyst website Trading Economics. The lower prices, according to the site, are related to recent evidence of increased supply. This contrasts with the longer-term expectations of bullish demand and higher prices.

Shielding | Special Issue on the 11th International Conference on Radiation Shielding and the 15th Topical Meeting of the Radiation Protection and Shielding Division (Part 2) / Radiation Protection | doi.org/10.13182/NT09-A9226

A shielding layout for a 40-MeV electron linac is presented. The linac building consists of 15-cm concrete roof and walls, and 2-m-thick shielding walls for horizontal shielding. No shielding roof covers the linac, which reduces the capital cost of the facility building. Though the present shielding layout allows an operation of up to 11.8-W averaged beam power, experimental dose equivalent rates are found to be much greater than that predicted by the skyshine formula. Monte Carlo (MCNP 4C) simulations indicate considerable contributions of radiation scattering by the thin roof and walls.
