Abstract
Red-thermoluminescence (RTL) dating was applied to quartz grains from a flat roof-tile of “Shin-Yakushiji” temple, Nara, built in Japan, probably 1258 years ago. Based on overlapping patterns with other roof-tiles, one flat roof-tile was separated into several zones. The equivalent doses were accurately evaluated to be 4.4–5.1 Gy for each zone. The evaluation of annual doses has been done under the consideration of overlapped numbers of roof-tiles and soil layers under the roof-tiles. Evaluated RTL ages were in good agreement with the construction date of the temple. The present evaluated age was the youngest one within several ages we previously have been deduced from the RTL dating.
