Memo to file -3- i f Air Force (PACE) ere active on Runit but their activities to date and anticipated should not seriously affect the cleanup job. Aomon-Biijiri-Rojoa: Biijiri and Rojoa are relatively clean with surface gamma levels of 10 “hr or less and some metal scrap reading as high as ko hr. Aomon also is fairly clean with the exception of one burial site in the northern sector and two ground zeroes also in the north. One of the latter reads about 3mr/hr. There are also two monuments on this island on concrete slabs upon which a protective 3" layer of concrete has been poured. Although the marker plate from one of these has been removed, it is assumed to indicate the presence of g& contamination. The protective concrete is being eroded and cracked. The contaminated slabs themselves are too large to move and will probably have to be broken up if removal is required. In addition, there is a large quantity of iron scrap on Aomon (probably activated). Engeki: 1 Potentially one of the most useful islands for agriculture, ’ Engeki presents a substantial cleanup job. There is a large amount of metal scrap, both buried and on the surface with readings ranging as high as 12mr/hr. The PACE project will attempt to avoid using Engeki, but if its use becomes necessary will attempt to minimize the impact. Bogon and Bogairikk: Small islands, a moderate amount of scrap, with gamma readings relatively high on Bogon (up to 3004~/hr).
