Many communities around the world continue to suffer from the effects of radiation exposure, primarily from nuclear weapon testing, but also from the civilian use of nuclear power, and from the manufacture of materials used in both nuclear weapon and nuclear power production. While the epidemiological issues related to radiation exposures have been the subject of many studies, the social and cultural effects on families and communities has been neglected. The Global Hibakusha Project in engaged in a comprehensive study of the social and cultural fallout from atmospheric nuclear weapon testing on the many test site communities of the early Cold War. Additionally, the GHP is also working to create linkages between technology savvy youth in hibakusha communities through the utilization of Web 2.0 technologies. Whereas previous movements to link hibakusha communities were necessarily dependent on the work and relationship of community leaders, the internet age has opened up the possibility of broader, youth driven community formation. The establishment of an online community of hibakusha youth from around the world will lead to the creation of future community leaders, and sustainable relationships between hibakusha from disparate communities. This paper will detail the work to date and future plans of the Global Hibakusha Project.
