5th International Conference on Radioecology & Environmental Radioactivity

Welcom address by Jean-Christophe GARIEL, 

IRSN, Deputy Director General, Health and Environment and Per STRAND (DSA, Director General and President IUR)

Welcome to the 5th International Conference on Radioecology & Environmental Radioactivity, 4-9 September 2022, Oslo, Norway !​

Pending the possibility of organizing a face-to-face conference since 2020, an online event was organized in 2021. 2022 is the year of the "re-birth" of the face-to-face conference cycle.

The aim of ICRER-2022 is to review and discuss recent achievements in radioecology, environmental radioactivity and related disciplines, as well as to promote continued development in these subjects in order to improve the radiological protection of humans and the environment.

ICRER-2022 will cover the acquisition of basic scientific knowledge in research dedicated to human and biota exposure situations for a wide range of radioactive sources (anthropogenic and naturally occurring radionuclides), as well as identifying new societal needs along with technical requirements for regulators and industry.

The conference scope is large covering environmental monitoring and field work, radiation effects studies, advances in analytical methods/metrology as well as model development and validation. The latest updates on integrated and graded approaches for human and environmental radiological risk assessment will be of interest as will results from research programmes on the environmental consequences of the Fukushima Daiichi and Chernobyl accidents. Design of appropriate emergency preparedness routines will be another focus area, along with developments regarding laws and regulations that protect man and ecosystems from the effects of ionising radiation.

Organized by Norwegian Radiation and Nuclear Safety Authority (DSA), Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and the International Union of Radioecology (IUR) in cooperation with IAEA, FAO, UNSCEAR, OECD/NEA, EC-JRC, ICRP, AMAP, CERAD CoE, Journal of Environmental Radioactivity and European Radioecology Alliance.​​​
