-3(c) ERDA's preliminary report had a table indicating that men and women would be spending 20 to 15% of time, respectively, in the interior of the island. Question was raised whether this time frame had been predicated on current period or situation when the coconut groves would be in full production. Reply: Nat Greenhouse of Brookhaven National Laboratory stated that these time estimates were based on projections of when coconut trees would be fully bearing. (d) Mr. Allen inquired as to relationship between thyroid abnormalities in Rongelapese individuals and possible beta-gamma residual radiation on Rongelap Island. Reply: Dr. Conard stated that it was believed that all thyroid cases were result of fallout experienced by the individual. The Rongelapese exposed to fallout received an internal dose to the thyroid gland from radioactive isotopes of iodine. (e) Mr. Allen indicated that there were indications of poison fish in the Bikini Lagoon although this was not necessarily related to the atomic testing program. He wondered though, what affect any restriction on local fish might have on the diet component of the people of Bikini on their return. Reply: Mr. Roger Ray noted that the University of Hawaii was conducting research on the general problem of fish poisoning. Presently, short of testing each fish with a “mongoose” tester, scientists have not come up with adequate answers. ~ Distad DeBrum pointed out that it is usuallythe Red Snapper which falls into the dangerous category. Pattern is found throughout the Marshalls. Problem though is that there is no consistent pattern, i.e., at one time of year, Red Snapper may be poisonous, not another time, etc. 3. Prospective Aerial Survey Mr. Joe Deal, ERDA, presented a brief synopsis of legacies of nuclear testing in the Pacific. The problems from Pacific weapons testing, the fallout and fallout pattern, and the need for an aerial radiological survey were described. Summary in chart form is appended as Appendix "C." Mr. George Allen, MLSC, raised a number of questions. “s ewe eR meeee ne Tyo a Fe 7 Te ¢ la, wet wa 5 eee “ a a cee rg , TE yt’ . ogee. ‘ wa WO, “5° 4! noe Ms : rg lle ‘ . wet .
