Residual changes in the skin from the previous
beta burns were present in 13 Rongelap people
andin one Ailingnae individual, mostly on the
back of the neck, the antecubital fossae, and the
dorsum ofthe feet. These changes were not severe
and consisted grossly of alterations in pigmentation in areas showing slight atrophy and scarring
of the skin. In some cases pigment was increased
and in others pigmentation had not completely
returned. In other instances both pigmentation
and lack of it were present in the samelesion,giving a blotchy and uneven color. In only a few

cases (several lesions on the dorsum ofthe feet and
one ear lesion) was there sufficient scarring to result in adhesions of the skin to subcutaneous tissues.
Biopsies were taken from four lesions and from
similar areas in unirradiated individuals for comparison. Microscopically no changes were noted
suggestive of neoplastic changes. Some lesions
showed thickening of the corium by bands of
collagen fibers, but this was no more extensive
than that observed in biopsies a year ago.
