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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Line-beam response function (LBRF) and conical-beam response function (CBRF) data for gamma-ray skyshine are generated using the EGS4 code in an arbitrary geometry for energies ranging from 0.1 to 10 MeV at all the emitted angles up to a distance of 2000 m from the source. The skyshine dose is calculated for the air kerma, exposure, ambient dose equivalent H*(10), and effective dose E with anterior-posterior and isotropic irradiation geometries.A response function with a four-parameter empirical formula,R(E,,x) = [fraktur R]E(/0)2 exp(a + cx/0)xb+dx/0,can be used to approximate the LBRF and CBRF with good accuracy. The values of the four parameters a, b, c, and d are determined for a given beam energy and direction by fitting the four-parameter function such that the maximum fractional deviation of the LBRF and CBRF values is minimized for a set of discrete source-to-detector distances. The parameter set is selected to realize the interpolation of LBRF and CBRF in relation to the energy and direction by the interpolation of these parameters. Consequently, discrete LBRF and CBRF data are converted to continuous data with regard to both energy and direction.The evaluation of gamma-ray skyshine dose analyses can be accomplished easily and quickly by using the four-parameter formula.These data can be downloaded in Excel format from http://rcwww.kek.jp/rc_en.html as "Data Library of Line- and Conical-Beam Response Functions and Four-Parameter Empirical Formula in Approximating Response Functions for Gamma-Ray Skyshine Dose Analyses."
