Table 21 lists the 30-y integral doses for Likiep and Rongelap Islands by exposure pathway. The contributions from the external gamma pathway for most outer atolls are less than 30% of that from the food ingestion pathways for the MLSC diet when imported foods are available. For atolls more in line with the trajectory of the Bravo cloud, the external gamma pathway contribution is between 40 and 70% of the total dose for the MLSC diet. For the BNL diets and the MLSC diet when imported foods are unavailable, the dose from the ingestion pathway greatly exceeds that from the external gamma pathway. The contribution of the marine, cistern water, and inhalation pathways is very small relative to the terrestrial food chain pathway. Again, the results for Rongelap and Likiep Islands are similar to those for the other atolls and islands. Se 46
