The third medical examination of A-bomb survivors residing in the U.S. was performed in San Francisco, Los Angeles, Seattle and Honolulu during the period 6-28 May 1981. The test results were studied and the actual state of the survivors in the U. S., was reviewed as explained hereunder.

1) The number of survivors actually registered with the Committee of A-bomb Survivors in the U.S. is 491 (133 males and 358 females) of whom 57.2% are U.S. citizens. Those exposed in Hiroshima accounted for 91.8 %. The mean age was 53.3 ± 8.9, thus they were more than 3 years younger than their counterparts in Hiroshima. The present addresses of the survivors are distributed over 15 states, but those in California constitute 77.6% of the total, and when those residing in the states along the west coast and Hawaii are added the rate increases to 95.9 %.

2) Those who underwent health examination numbered 166 (45 males and 121 females), and comparison of the U.S. survivors against the Hiroshima survivors showed there to be a difference in the following points. The prevalence of hypertension was lower among the U. S. survivors, but RBC counts and hemoglobin concentration were significantly higher. The same was observed for blood lipids with hypercholesterolemia and hypertriglyceridemia being found at a significantly higher rate in the U. S. survivors.

3) Those free of clinical abnormalities in this survey were 37.3 %, and the rest requited dietary guidance, follow-up observation, detailed examination or treatment. Those with diseases which are considered would make them eligible for health management allowance if in Japan, accounted for 18.7 %.
