Although not required, it would be more efficient, both economically and scientifically, to have the data bank effort and the dose assessment effort carried out by the same organization. Even though the output of the data bank could be supplied to whoever is handling the dose assessment, it is most useful to be able to evaluate the data and design the input for the dose models in an integrated manner which would be more difficult if these two functions were separated. The dose assessment requirements of P.L. 96-205 will be met for the first 5 year period with the dose assessments made in 1979 for Enewetak, 1980 for Bikini, and those for Rongelap and Utirik which will be published in 1981 from data generated in the Northern Marshall Island Survey. Five years subsequent to each of these dose assessments an updated published assessment will be made. This cycle will be repeated every 5 years, and continue on a similar cycle until it is determined that the frequency of the assessment period can be decreased or perhaps terminated. 4.) Risk Analysis After the maximum annual doses and 30 and 50-year integral doses have been estimated, it will be necessary to estimate the increased genetic and somatic risk to the population. The risk should be estimated using the best information available on the increased incidence of cancer and genetic defects caused by radiation exposure such as that presented in the Nationa) Academy of Science Reports on the Biological Effects of Ionizing Radiation (BEIR Report). should accompany each dose assessment for each atoll. 45 A risk analysis
