This boat has been presumed to be exposed to the fallout of Bikini hydrogen bomb test. Gamma-ray measurements have been carried out for six wood samples and two soil Samples. Since the {sup 137}Cs concentration estimated for all samples were comparable to the fallout of the nuclear test, it was hard to judge whether the boat was definitely exposed to the Bikini fallout.
