5. Conclusion

The [BN 3 909] article is based on long-established and stabilized knowledge of radionuclides other than tritium and carbon-14. Radioecology experiments began in the 1960s and continued throughout the 1970s and 1980s. The 1980s and 1990s saw the development of models and calculation codes. These models were supplemented and partly validated by the results of measurements taken after the Chernobyl accident; they were then the subject of numerous international intercomparison and compilation programs. Research in these fields of radioecology, and hence the contribution of new knowledge, then...
