Dr. Tabatadze Serves on International Collaboration Committee May 7, 2015

George Tabatadze has been appointed as a member of the International Collaboration Committee (ICC) of the  Health Physics Society (HPS). He will begin his three-year term starting July 2015. Dr. Tabatadze previously served as an advisor for the committee in 2014. He has actively participated in planning the special session for the 2015 HPS annual meeting in Indianapolis, IN, including arrangements for the special speaker visit from the Georgian chapter of the Health Physics Society (Georgian Health Physics Association - GHPA). He also played a key role in nominating the GHPA president-elect for the 2015 HPS G. William Morgan lectureship.

Recently Published Research February 23, 2015

Findings based upon tissue donations to the USTUR continue to shape our understanding of internally incorporated actinides. In the early months of 2015, two scientific papers were published by USTUR faculty. Maia Avtandilashvili modelled the long-term retention of uranium hexafluoride (UF6) in an occupationally exposed Registrant, and Sergei Tolmachev coauthored a publication that mapped the distribution of actinides in lymph nodes from USTUR donors.

Avtandilashvili M., Puncher M., McComish S.L., Tolmachev S.Y. US Transuranium and Uranium Registries Case Study on Accidental Exposure to Uranium Hexafluoride. Journal of Radiological Protection. 2015, 35(1):129-151. Abstract

Vergucht E., De Samber B., Izmer A., Vekemans B., Appel K., Tolmachev S., Vincze L., and Vanhaecke F. Study of the distribution of actinides in human tissues using synchrotron radiation micro X-ray fluorescence spectrometry. Analytical and Bioanalytical Chemistry. 2015, 407(6): 1559-1566. Abstract

USTUR Active at Scientific Meetings November 17, 2014

USTUR faculty have participated in several scientific meetings during recent months.

Radiobioassay and Radiochemical Measurements Conference

Sergei Tolmachev and George Tabatadze attended the Radiobioassay and Radiochemical Measurements Conference in Knoxville, TN on October 27-31, 2014. This opportunity provided a valuable opportunity to network with other scientists in the field.

European Radiation Dosimetry Group

Sergei Tolmachev and Stacey McComish are active participants in a task group that is reviewing journal articles on the biodosimetry of internally deposited radionuclides. This work is conducted as a part of a joint effort between Working Group 7 (internal dosimetry) and Working Group 10 (retrospective dosimetry) of the European Radiation Dosimetry Group (EURADOS). Dr. Tolmachev and Ms. McComish attended the EURADOS plenary meeting in Warsaw, Poland on October 1-2, 2014. (read more)

Radiation Research Society Meeting

Sergei Tolmachev was invited to speak during the "Radiation Archives" session at the 2014 Radiation Research Society Annual Meeting in Las Vegas, NV on September 21-24, 2014. His presentation focused on samples available at NHRTR from both USTUR donations as well as collections such as tissues from the terminated Radium Worker study at Argonne National Laboratory.

Annual Health Physics Society Meeting

Sergei Tolmachev and Maia Avtandilashvili attended the 59th Annual Health Physics Society Meeting in Baltimore, MD on July 13-17, 2014. Dr. Avtandilashvili presented a case study of a worker who was exposed to plutonium as a result of a wound. She tested the NCRP wound model by modeling the worker's urinary excretion and organ retention using the Integrated Modules for Bioassay Analysis (IMBA) Professional Plus software. (read more)

George Tabatadze began work as a research associate in radiation measurements on August 1st. Dr. Tabatadze earned his Ph.D. from Idaho State University in 2012. His research was conducted using data from a USTUR registrant donation. As such, he is well acquainted with the mission and operation of the Registries. He is enthusiastic about joining the USTUR research team, and we look forward to working with him.

USTUR Director Adjunct Professor at Laval University May 7, 2014

The USTUR director, Dr. Sergei Tolmachev, was reappointed as an adjunct professor at Laval University, Quebec City, Quebec, Canada.

Dr. Tolmachev was first appointed as an adjunct professor in 2011, and his current term of appointment extends until June 2017.

Health Physics Society Meeting March 31, 2014

USTUR faculty are authors on two abstracts that will be presented at the 59th Annual Meeting of the Health Physics Society in Baltimore, MD, July 13-17:

M. Avtandilashvili, S. L. McComish, S. Y. Tolmachev. USTUR Whole-Body Case 0212: Testing NCRP Wound Model.

R. L. Kathren, S. Y. Tolmachev. Uranium Distribution and Concentrations in the Tissues of Whole-Body Donations to the USTUR.

A third abstract will be present research based upon USTUR data:

J. Zhou. Incorrect Analyses of Radiation and Mesothelioma in the US Transuranium and Uranium Registries.
