EURADOS Young Scientist Award goes to IRSN researcher


The work rewarded relates to an intercomparison proposed and implemented by LEDI as part of EURADOS. The intercomparison aimed to evaluate the internal dose received by nuclear workers, as part of epidemiological studies on the induced risks of uranium exposure. Sixteen participants evaluated the doses received by three professionally active nuclear workers between 1960 and the early 1980s, through raw data supplied by IRSN.
Estelle Davesne then analyzed all of the results obtained, determining the sources of uncertainty over the reconstituted doses based on epidemiological data. She was able to identify the parameters on which there was consensus (such as the ICRP's biokinetic and dosimetric models) as well as those which could be refined through modeling (such as lung absorption, exposure period, etc.). Using the first study, she will be performing a sensitivity analysis to evaluate the degree of influence of these parameters on dose estimates. It is the first intercomparison of this type, and the results will be particularly useful to epidemiologists in monitoring cohorts of workers.
Each year, the EURADOS Young Scientist Award recognizes work carried out by scientists under the age of 35 under the guidance of this network in the field of ionizing radiation dosimetry. The research will lead to scientific publications and presentations at international conferences.
The EURADOS permanent network is comprised of experts and reference laboratories in radioprotection, radiobiology, diagnosis and radiotherapy, and aims to support scientific and technical research in the field of ionizing radiation dosimetry in Europe and internationally. The main objectives are to align existing work practices, establish a dosimetry training approach and be part of the CONCERT European Consortium.
