In the present paper, the authors report the results of thermoluminescence (TL) dating of the bricks from a modern structure, and discuss the validity of this method. TL method is a typical and well-used tool for estimating the age of heated relics. In this research, TL dating method applied to the bricks of the brickwork foundation of an officer' s mess hall which were excavated at the site of the 53th Infantry Regiment on the campus of Nara University of Education. In 1909, the 53 Infantry Regiment was located in the site, where the campus of Nara University of Education is now located. The Infantry Regiment site was first discovered in 2008. This site was excavated continuously between 2008 and 2011. And, the samples were collected at the Infantry Regiment site in 2011. The samples were measured according to the protocol of multiple aliquot additive dose. The TL age averaged for all samples is 96±10 years before present. Thus the results of the present work indicate that the bricks were burnt in the period around the early 20th century. The results are consistent with the ages shown from the archaeological aspects of view. The TL dating method was successfully applied to the modern burnt bricks. And the above result suggest that TL dating method is a valid technique for the research on the history of modern times.

@beridox_tape @FelisCatusJpn ちょっと記憶から消えましたので調べたら2013年のようですね。割としっかり調査されてました。 PDF注意。https://t.co/jt60BiaWFK
