Variation of the Radiocarbon Content in Tree Rings During the Spoerer Minimum
This paper presents the variation of radiocarbon content in annual tree rings for the period AD 1413–1553, which includes the Spoerer Minimum period (AD 1415–1534). Since the variation of the production rate of 14 C is strongly related to solar activity, the variation of 14 C content in annual tree rings gives us information on the characteristics of variation of solar activity. We have studied solar activity during the grand solar minima, focusi…
Measurement of Radiocarbon Content in Leaves from Some Japanese Sites
We have measured radiocarbon contents in leaves collected from 15 sites in Japan, including mountain areas and big city areas for last three years. Comparing the radiocarbon contents in various areas, high 14 C concentrations (80–100‰ as δ 14 C) are seen for the leaves from the mountain and country sites. On the contrary, low concentrations (5–40‰) were observed for the leaves from city region, especially near the road with heavy traffic. These r…
The New Nagoya Radiocarbon Laboratory
A liquid scintillation counting apparatus that enables highly accurate measurements of 14 C has been constructed at the Solar-Terrestrial Environment Laboratory, Nagoya University. The main aim of the project is high precision year-by-year measurements of the 14 C content in tree rings of an old cedar tree from Yaku Island, Japan. We present the results of 14 C measurements on tree rings from the Agematsu region for recent decades to confirm the …
