Tony Riddell elected fellow of European radiological protection society

Tony Riddell has been elected a fellow of the Society for Radiological Protection in the United Kingdom. Mr. Riddell is an adjunct faculty member at the USTUR, and is the internal dosimetry group leader in the Radiation Hazards and Emergencies Department at Public Health England.

2020 Newsletter

In December, the USTUR mailed its 2020 Registrant newsletter to living Registrants and deceased Registrants’ next of kin. This year’s newsletter provided an update on the challenges and opportunities associated with Covid-19 work restrictions, as well as other activities at the USTUR.

USTUR director reappointed as KEEA technical advisor

Dr. Sergei Tolmachev has been reappointed as a technical advisor at Kyushu Environmental Evaluation Association in Japan. He will serve a two-year term from April 1, 2020 to March 31, 2022.

SAC member to give Parker Lecture in April

The USTUR invites you to join us as USTUR Scientific Advisory Committee member, Luiz Bertelli, discusses the radiological accident in Goiânia, Brazil during the Spring 2020 Herbert M. Parker Lecture. Dr. Bertelli is an internal dosimetrist at Los Alamos National Laboratory. He has over 40 years of experience with internal dosimetry modeling and interpretation of monitoring for radiation workers, including 18 years in Brazil. The Parker Lecture Series is sponsored by the Herbert M. Parker Foundation in partnership with WSU Tri-Cities.

Note: this lecture was rescheduled due to COVID-19.

Anthony Riddell from Public Health England joins adjunct faculty to USTUR

Tony Riddell has been appointed as an adjunct faculty member with the USTUR, he has more than thirty years’ of internal dosimetry experience and also within related areas of research such as epidemiology and radiobiology. Mr. Riddell leads the Internal Dosimetry Group at Public Health England (PHE), where he is responsible for the management and delivery of the United Kingdom’s national internal dose assessment capability and a program of research which supports this capability and the work of organisations such as the International Commission on Radiological Protection.

Having shared research interests in areas such as radionuclide metabolism, dosimetry and potential exposure risks, USTUR has collaborated with Mr. Riddell and PHE over many years. In 2018, Mr. Riddell facilitated a Memorandum of Understanding (MOU) between the USTUR and PHE’s Centre for Radiation Chemical and Environmental Hazards (CRCE) to help further this mutually beneficial relationship. Among other things, this MOU allowed PHE to share its newly developed internal dosimetry software, Taurus, with the USTUR for research purposes. The base model of Taurus is designed for operational dose assessment, but the USTUR will make use of an advanced version of the software to study the movement of actinides, such as plutonium, through the human body, and to calculate doses from intakes of those elements. The USTUR looks forward to continued collaboration with Mr. Riddell and PHE-CRCE.

Special issue of Health Physics journal features USTUR research

The August issue of Health Physics was dedicated to a special issue on USTUR research. Presentations from the USTUR’s one-day special session of the 2019 Health Physics Society meeting were published as full length articles, along with an introduction to the special issue and a summary of the roundtable discussion. The special issue was published as one of several activities designed to commemorate 50 years of research at the USTUR.
