In December, the USTUR mailed its 2025 Registrant newsletter to living Registrants and deceased Registrants’ next of kin. This year’s newsletter included two guest articles from the scientific director of the Million Person Study, Lawrence Dauer. The first article introduced the MPS and the second discussed an observed association between Parkinson’s disease and radiation dose. The newsletter also included the USTUR director’s annual “Direct from the Director” letter, information about a proposal to create a Radiological and Nuclear Security Leadership Academy at WSU, an update on the USTUR’s follow-up urine collection program, a summary of the MPS special session at the 2025 American Public Health Association meeting, and a brief history of the Oak Ridge Associated Universities consortium, which WSU has been asked to join.
