REI in 2023 will be the 21st international conference dedicated to research relating to radiation effects in insulators and non-metallic materials. In 2023, discover REI in Fukuoka. Fukuoka is one of Japan's largest cities, and it is the administrative, economic, and cultural center of the southernmost island of Kyushu. It is one of the country's most progressive cities.
What’s more, Fukuoka is chosen as New York Time’s “52 Places to Go in 2023”.
Since the first REI conference in Arco, Italy, in 1981, REI has been the international forum held every two years to present and discuss the latest achievements in the field of insulating materials modification through different kinds of radiation source (ions, electrons, neutrons...). The REI conference is one of the most prominent and long running conference series in the field of radiation effects in materials.
