On April 20^th I had the opportunity to present my RadoNorm Early Career Researcher Project and the challenges we have been facing to develop a biokinetic model to assess embryo/fetus doses due to radon intakes by the mother at the Conference of the Canadian Association of Radon Scientists and Technologists (CARST 2022, April 20^th – 22^nd). The online session in which I presented was called: “Working together for Tomorrow” and 120 people attended it. The title of my presentation was “Challenges of developing a comprehensive biokinetic model to assess embryo/fetus doses due to radon intakes by the mother”. The aim of the presentation was to point out the general demands to build a specific biokinetic and dosimetric model for the embryo and fetus as a result of intakes by the mother, the available theoretical and experimental data specific for radon and radon progeny, and what could be the next steps to overcome these challenges in the frame of my RadoNorm project. The other presentation in the session was by Dr. Annette Röttger, the Head of the Division 6 Ionizing radiation of the German National Metrology Institute (PTB, Germany), and the title was “Traceability of radon measurements at the environmental level”, an update of the research group’s most recent discoveries on the topic.
