The major contribution to the terrestrial food chain comes from food such as. coconut, breadfruit, Pandanus, etc. Looking specifically at the terrestrial foods, coconut contributes a major share of the dose because of its 1376. concentration and the high intake of coconut. The annual dose rates and 30- and 50-y integral doses are calculated for two dietary conditions to indicate the range of doses based on current diet surveys. The doses are calculated assuming that people would be living full time on the listed island, with all of their local foods from that island. This includes islands at atolls that are currently uninhabited. At each inhabited atoll we have included the islands that we were able to determine were being used as a residence or partial residence island or as major agricultural island. At uninhabited atolls we have included the major islands that might possibly be used for residence. All of the inhabited atolls except Rongelap and many of the uninhabited atolls have annual doses of less than 30 mrem/y, regardless of the assumed diet. The range is from about 3 to 6 mrem/y for the MLSC diet to 20 to 29 mrem/y for the BNL diets. The doses at uninhabited Ailinginae Atoll would range from 13 to 90 mrem/y for the MLSC and BNL diets, respectively. The doses at the southern residence islands at Rongelap Atoll range from 35 to 58 mrem/y for the MLSC diet and from 58 to 135 mrem/y for the BNL diet. If Rongerik were continually inhabited, the respective range of doses would be 42 to 66 mrem/y and 69 to 90 mrem/y. If the northern islands at Rongelap were inhabited continuously, the estimated doses for the various islands would range from 90 to 330 mrem/y for the MLSC diet and from 150 to 580 mrem/y for the BNL diet. The 30-y integral doses for Likiep, Wotho, Ujelang, Mejit, Ailuk, Taka, Jemo, and Bikar all fall between 0.055 and 0.14 rem for the MLSC diet and between 0.09 and 0.7 rem for the BNL diet. Doses for Utirik range from 0.25 to 0.72 rem for the MLSC diet and the BNL diet, respectively. If Rongerik were inhabited continuously, the estimated doses would range from 0.94 to |.6 rem for the MLSC diet and 1.5 to 3.8 rem for the BNL diet. The inhabited southern islands of Rongelap Atoll have 30-y integral, whole-body doses for the MLSC diet ranging from 0.76 to 1.3 rem and for the BNL diet they range from 1.2 to 2.5 rem. If the northern islands of Rongelap were populated continuously, the estimated doses for the MLSC diet would range from 2 to 7.4 rem and for the BNL diet they would range from 3.4 to 14 rem.
