Seven growth forms of the species Neogoniolithon frutescens (Foslie) Setchell and Mason, Porolithon onkodes (Heydrich) Foslie, P. craspedium (Foslie) Foslie, and P. gardineri (Foslie) Foslie found on Rongelap Atoll are described in detail. Two of the growth forms are new combinations: N. frutescens f. flabelliformis (Foslie) Lee and P. gardineri f. abbreviata (Foslie) Lee. Porolithon craspedium and P. gardineri seem to be especially adapted to the atoll environment. The largest individuals and greatest density of organisms were produced by P. craspedium f. craspedium at the leeward reef margin and P. gardineri f. subhemisphaerica at the windward reef margin. With the exception of P. onkodes, a somewhat ubiquitous species, the distributional pattern displayed by the different species on the reef flat at Rongelap indicates that each has a narrow tolerance range for local variations in the environment.

We report on measurements of external gamma radiation on 9 islands in 4 atolls in the northern Marshall Islands, all of which were affected by the US nuclear testing program from 1946 to 1958 (Enjebi, Ikuren, and Japtan in Enewetak Atoll; Bikini and Enyu in Bikini Atoll; Naen in Rongelap Atoll; and Aon, Elluk, and Utirik in Utirik Atoll). We also report americium-241, cesium-137, plutonium-238, and plutonium-239,240 activity concentrations in the soil samples for 11 islands in 4 northern atolls (Enewetak, Japtan, Medren, and Runit in Enewetak Atoll; Bikini and Enyu in Bikini Atoll; Naen and Rongelap in Rongelap Atoll; and Aon, Elluk, and Utirik in Utirik Atoll) and from Majuro Island, Majuro Atoll in the southern Marshall Islands. Our results show low external gamma radiation levels on some islands in the Enewetak Atoll and Utirik Atoll, and elevated levels on Enjebi Island in the Enewetak Atoll, on Bikini Atoll, and on Naen Island in the Rongelap Atoll. We perform ordinary kriging on external gamma radiation measurements to provide interpolated maps. We find that radionuclides are absent from all Majuro soil samples, and that they are present at highest activity concentrations in samples from Runit and Enjebi islands (Enewetak Atoll), Bikini Island (Bikini Atoll), and Naen Island (Rongelap Atoll). We contextualize all results by making comparisons between islands and to various standards, as well as to regions of the world affected by nuclear accidents. We also discuss implications for informed decision-making by the Marshallese and local atoll governments and their people on issues pertaining to island resettlement.
