23rd EURADOS Webinar: The European Intercomparison of In-Vivo Monitoring Laboratories: The EIVIC-2020 Project

All information
23rd Webinar - EIVIC

Online event
Starting time: 13:30 CET



The objective of the EIVIC-2020 project was to assess the implementation of the individual monitoring requirements of the Basic Safety Standards (BSS) Directive in EU Member States based on in-vivo measurements and receive an overview of the capabilities and performance of whole-body counters in Europe.
This exercise was supported by the European Commission (Directorate-General for Energy) in Luxembourg under the contract ENER/2019/NUCL/SI2.811157 and organised by EURADOS (European Radiation Dosimetry Group), the Institut de Radioprotection et de Sûreté Nucléaire (IRSN, France) and the Federal Office for Radiation Protection (BfS, Germany) in collaboration with the Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT, Spain) and the Karlsruhe Institute of Technology (KIT, Germany).
It was organised between October 2019 and June 2022 and dedicated to whole-body measurement of gamma emitters in several tasks selected that cover the range of such possible measurements associated to different intake scenarios. In total, 43 installations from 21 countries took part in the intercomparison exercise.
The measured data were compared with reference activity values to evaluate the corresponding bias according to the standards ISO 28218 and ISO 13528. This report gives a summary of the results of the different tasks. In general, the results are good, and most facilities are in conformity with the criteria for the bias and z-scores in the ISO standards. Additionally, it was tested if the results can be attributed to several organisational and metrological properties of the participating laboratories.

María Antonia López
Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT), Madrid, Spain
María Antonia López is the Head of the Internal Dosimetry Group at CIEMAT, in Madrid , Spain. She is the secretary of ICRP Committee 2 on “Doses from Radiation Exposure” and she is the coordinator of the TG on “Internal Dosimetry for Emergency” within EURADOS. She was the leader of the WP1 of the EIVIC Project in charge of the communication with participants and stakeholders.

Didier Franck
Institut de Radioprotection et de Sûreté Nucléaire (IRSN), Fontenay-aux-Roses, France
Didier Franck is the Deputy Head of the Research Dosimetry Department at the Nuclear Safety and Radiation Protection Institute Radiation Metrology Section and of the Dosimetry Group (IRSN), France. He is also Co-Director of the doctoral School of Nuclear Physic at Paris Saclay University (UPS).
He obtained his PhD at the University Paris Saclay (France) in 1986. After a 2 year postdoctoral fellowship at Washington University (USA), he joined IRSN in 1993 (formerly called IPSN).
At IRSN he led an expertise and research laboratory in the area of internal dosimetry and in vivo monitoring until 2017. Research projects included the development of new methods for in vivo monitoring based on Monte Carlo calculation but also medical applications in nuclear medicine, including alpha therapy and micro dosimetry, as well as the development of news tools for the crisis management of internal contamination. As expert he participated to numerous national and international projects such as the development of national network of in vivo laboratories and the organization National Intercomparison in vivo monitoring exercises as well as the development of the Technical Recommendations for Monitoring Individuals for occupational Intakes of Radionuclides (TECHREC) founded in 1916 by EC.
He is also a member of the Working group “internal dosimetry” (WG7) of the European Radiation Dosimetry Group (Eurados) as well as member of the groups WG13 (internal dosimetry) and convenor of the WG25 group (Population Monitoring Following Radiological Accidents) of the International Organization for Standardization (ISO).

Oliver Meisenberg
Federal Office for Radiation Protection (BfS), Oberschleißheim, Germany
Oliver Meisenberg is head of the Internal Monitoring Workgroup at the Federal Office for Radiation Projection (BfS), Germany. He graduated in physics from the Technical University of Munich with a focus on radiation protection, medical physics and nuclear engineering. From 2006 to 2014 he was employed at the Experimental Radioecology Workgroup at Helmholtz Munich, where he measured and modelled the properties of natural and artificial radionuclides in the environment and in homes. From 2014 to 2019 he was the head of the internal monitoring service at the BfS office in Neuherberg (Munich). Subsequently he became the head of the workgroup, which runs two internal monitoring services and offers international in-vivo and in-vitro interlaboratory comparisons on a regular basis. His scientific focus is on the development of new methods in internal monitoring, the assessment of internal radiation exposure in the public, and the preparation for radiological accidents.

Tiffany Beaumont
Institut de Radioprotection et de Sûreté Nucléaire (IRSN), Fontenay-aux-Roses, France
Tiffany Beaumont is a researcher in internal dosimetry of the Internal Dose Assessment Laboratory (LEDI) at IRSN. She obtained her PhD at the University of Paris-Saclay (France) in 2018. At IRSN, from 2018 to 2020, she was in charge of the technical organisation of the national and international intercomparison. Her scientific focus was also on development of methods for monitoring people following accidental and deliberate releases of radioactivity to the environment, in particular for children and persons of reduced mobility. Since 2020, she conducts research in internal dosimetry and developed innovative calibration phantoms dedicated to in vivo measurements and nuclear medicine. She is member of the the ISO TC85/SC2 Working Group 13, the Internal Dosimetry Working Dosimetry Group (WG7 EURADOS) and the “Research and Health Group” of the French Society of Radiological Protection (SFRP).
