This paper surveys our recent studies on fluctuation in prehistoric population of each local area in Jomon or Japanese neolithic period, and infers the reasons for the fluctuations in archaeological contexts. Archaeological demographic reconstruction in Japan has been based on numbers of archaeological sites or structures such as pit dwellings. In Japanese archaeology, pottery chronology has been established in detail. In recent years, many 14C data of various pottery types in Jomon period...
On the Precision and Accuracy of Radiocarbon Dating (2015)
Radiocarbon dating in the modern age is a precise experiment requiring an understanding of nuclear physics using accelerators It require measurements on the order of parts per trillion of carbon 14 nuclei in samples. Although most of the procedures of radiocarbon dating are standardized these days, the final results of the measurements have limitations on precision and accuracy that require careful verification before final acceptance. Recently, our group has carried out radiocarbon dating on...
