2015 Registrant newsletter mailed

Each year, the USTUR mails a newsletter to living Registrants, and to the next-of-kin of those Registrants who have already passed away. This year’s newsletter summarized plans for the USTUR’s upcoming 50th anniversary, visits from DOE officials, recently published research, and a new SAC member, and information about the new Manhattan Project National Historical Park.

Director attends ICRP symposium in Seoul, South Korea

The USTUR’s director, Sergei Tolmachev, attended the International Commission on Radiological Protection’s (ICRP) 3rd International Symposium on the System of Radiological protection in Seoul, South Korea, October 20-22, 2015. This symposium was “an opportunity to hear about ICRP’s recommendations and work-in-progress directly from ICRP members, to have your views on this work heard, and to network with ICRP members and radiological protection colleagues from all parts of the world.”1 Topics included the science behind radiation doses, and new developments in understanding radiation effects. Between sessions, Dr. Tolmachev discussed plans for future collaborative research.

DOE AU-1 acting under secretary visits

On August 25th, DOE’s Acting Associate Under Secretary for Environment, Health, Safety, and Security – Matthew Moury – visited the USTUR. The visit started at the office, where Dr. Tolmachev provided an overview of USTUR research, history, and vision for the future. Following his office visit, Mr. Moury visited the USTUR laboratory where he viewed the autopsy facility, and Dr. Tolmachev presented a step-by-step description of radiochemical tissue analysis: from a frozen sample to an α-spectrometric counting source. Specifics of actinide α-spectrometric measurements were explained by Dr. George Tabatadze.


Uranium paper

Former director, Ronald Kathren, and current director, Sergei Tolmachev, published a paper in Health Physics. The article, “Natural Uranium Tissue Content of Three Caucasian Males”, discusses the uranium content and distribution in three USTUR donors who were not occupationally exposed to uranium.


Tolmachev on Japan Journal of Health Physics editorial board

USTUR director, Dr. Sergei Tolmachev,  has been reappointed to serve on the editorial board for the Japanese Journal of Health Physics (JJHP) from August 2015 to July 2017.  He worked in Japan at the Japanese Atomic Energy Research Institute (JAERI), Tokai-mura and the National Institute of Radiological Sciences (NIRS), Chiba before joining the College of Pharmacy faculty in January 2007. Dr. Tolmachev has served on the JJHP editorial board since November 2009.

Gonzales and Feinendegen visit USTUR, tour lab

On April 5, 2015, Abel Gonzales (former member of ICRP Main Commission) and Ludwig Feinendegen (Professor Emeritus, Nuclear Medicine, Heinrich-Heine University Düsseldorf, Germany) visited the USTUR. Dr. Tolmachev provided a brief overview of the USTUR history, past and present achievements, and laboratory tour to the guests. Given the unique resources available at the Registries, Dr. Gonzales expressed surprise that the USTUR does not contribute to the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) activities related to the biological effects of uranium.
