U.S. Transuranium and Uranium Registries Learning from Plutonium and Uranium Workers



  • 2023 Newsletter

    In December, the USTUR mailed its 2023 Registrant newsletter to living Registrants and deceased Registrants’ next of kin. This year’s newsletter included a note from the USTUR’s director, as well as information about the USTUR’s special session at the Health Physics Society’s winter workshop on internal dosimetry; resumption of in-person advisory committee meetings and active inventory of historical NHRTR samples; and background information about the radium studies that were carried out by Argonne National Laboratory and other institutions.

  • Dr. Tabatadze visits research institution in Spain

    George Tabatadze visited the Centre for Energy, Environmental and Technological Research (CIEMAT) in Madrid, Spain on June 21, 2023. CIEMAT staff provided him with a tour of multiple laboratories, including their whole body counting facility, ICP-MS lab, bioassay lab, and neutron dosimetry lab. While there, he had many good discussions with CIEMAT staff including conversations about USTUR materials and research.

  • USTUR faculty participate in international dosimetry meeting

    Sergei Tolmachev, George Tabatadze, and Maia Avtandilashvili attended the annual European Radiation Dosimetry Group (EURADOS) meeting in Porto, Portugal from June 12-15. This year’s annual meeting included a EURADOS school on the “contribution of dosimetry in the field of nuclear emergency preparedness and radiological accident management” as well as meetings of the EURADOS working groups (WG). USTUR faculty participated in the WG7 task group on internal dosimetry, and Maia Avtandilashvili provided an example of a plutonium contaminated wound case for the EURADOS/Radiation Emergency Medical Preparedness and Assistance Network (REMPAN) wound contamination project.

  • USTUR data quality objectives published

    The USTUR has completed its data quality objectives (DQO) document, which addresses the sample collection and data analysis needs in support of the United States Transuranium and Uranium Registries’ (USTUR) mission. The DQO process was originally developed by federal agencies to ensure that data of acceptable completeness and sufficient quality would be available to inform decisions about environmental cleanup. The USTUR generally does not make decisions based on its radiochemical measurement data, but rather uses the data it generates to quantitatively describe the biokinetics of uranium and transuranium elements in the human body. In this document, the USTUR presents its … » More …

  • Welcome Xirui Liu!

    We want to welcome the newest member of the USTUR research faculty, Xirui Liu. Ms. Liu has worked with the USTUR as a student collaborator since 2019, where her research focused on using autopsy reports to determine how often the underlying causes of death found on death certificates are incorrect. Ms. Liu has both a master’s degree in health informatics from Weill Cornell Medicine (2022), and a master’s in public health in international health and development from Tulane University (2021). She also earned her Bachelor of Medicine, Bachelor of Surgery degree from Huazhong University of Science … » More …
