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.

The neutron yields of plutonium-beryllium (α,n) sources, made of nominal 239Pu, are increasing due to the buildup of 241Am, an alpha emitter, from the beta-decay of 241Pu which is present in these sources. Measured increases in yields are compared with predicted increases based on the isotopic composition of the plutonium used in these sources. In cases where the isotopic composition was not previously known, the composition was deduced from calorimetric measurements. Sources were found to have initial rates of increase of up to 2% per year. In all cases except one the measured rate of increase was in agreement with the predicted rate.
