Variation of 14 C in Japanese Tree Rings Related to the Fukushima Nuclear Accident
Radiocarbon ( 14 C) analysis was performed on Japanese cedar (Cryptomeria japonica) tree rings from Koriyama, Fukushima prefecture. Our primary aim was to detect any 14 C release from the Fukushima Dai-ichi nuclear power plant accident on 11 March 2011. We also completed and assessed the 14 C level in Japanese tree rings for the period of 1990–2014 because of the lack of environmental 14 C results in the Japanese island that time. For this reason…
Radionuclides in Ancient Relics Obtained from the Matsusaki Site and the Hirohata Shellmound on the Pacific Coast of Japan
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 enviro…
