We compared 2 archaeological relics of different preservation environments, white substances adhering to a vessel from the Matsusaki site and to earthenware from Hirohata, by measuring their environmental radioactivity, 14 C, 228 Ra/ 226 Ra, 234 U/ 238 U, and 87 Sr/ 86 Sr, and major element contents (Ca, Sr, Mg, Fe, and Mn). The results showed that the 2 materials were somewhat different and also reflected differences in their preservation environments. The chemical elements that were more abundant in the Matsusaki sample than in the Hirohata sample, Fe, Mn, 238 U, and 232 Th (parent of 228 Ra), are also abundant in seaweed or seagrass. Contamination by 14 C derived from rainwater after atmospheric nuclear tests was clearly observed in the white substance from Hirohata
