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.
