USTUR/COP PhD student gives three presentations in March

BRASCON 2016 Dumit thumbUSTUR/College of Pharmacy PhD student, Sara Dumit, gave three presentations in March.

The first was a seminar presentation given to College of Pharmacy faculty and students as a part of the college’s graduate research seminar class. Ms. Dumit summarized her work to fit urine and lung data from USTUR case 0785 using ICRP’s biokinetic models. » More …

Lecture for Internal & Environmental Dosimetry Class

In March, Maia Avtandilashvili provided a 2-hour lecture to students in WSU’s Internal and Environmental Dosimetry class (ENVR_SCI 523). Dr. Avtandilashvili introduced students to the Integrated Modules for Bioassay Analysis (IMBA) internal dosimetry software, and gave examples of how IMBA can be used as a tool to estimate radionuclide intakes from bioassay data such as urinalysis or in-vivo body count results.

Lecture and Lab Class for Radiation Instrumentation Students

In December 2015, Dr. George Tabatadze provided a 2-hour lecture and 3-hour laboratory practice to students in the Radiation Instrumentation class (ENVR_SCI 520). The class was offered by the Department of Environmental Sciences as part of WSU Tri-Cities’ Graduate Certificate Program in Radiation Protection. The topic of the lecture was solid-state charged particle detectors.

Dr. Tabatadze gives presentation at measurements conference

Tabatadze RRMC 2016The USTUR’s George Tabatadze and Elizabeth Thomas attended the 61st Annual Radiobioassay and Radiochemical Measurements Conference (RRMC) in Iowa City, IA, October 25 – 30. The USTUR laboratory recently analyzed a MAPEP soil sample to validate the Registries’ tissue analysis protocol for high-fired plutonium oxide. Dr. Tabatadze presented the results of this effort at the meeting.

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.
