Abstract

Some Japanese old porcelain samples, manufactured after middle of Edo-era (approximately 1600 AD), were initially investigated using thermoluminescence phenomena. Disc samples 9.4 mm in diameter and 1 mm thickness), prepared from the porcelain samples, were subjected to the thermoluminescence colour imaging (TLCIs) after artificial radiationexposure. Almost all porcelains showed red-TLCIs, giving homogeneous distribution except a few granular red patterns in the oldest porcelains, while the all earthenwares resulted in the granular patterns due to both blue and red grains as remaining minerals after burning On the basis of TLCIs results, the RTL-chronological method was applied using the porcelain discs and a highly sensitive RTL-measuring apparatus, which was installed with a light pipe (10 mm core-rod type glass) and a biotite light shielding plate to eliminate the black radiation. Naturally accumulated RTL, rendering extremely faint intensity, has been quantitatively determined and both regeneration and additive dose techniques were applied. As a result, some RTL-ages, concordant with the estimated ones, were obtained, resulting in possibility enable to estimate very young ages up to 30 years for porcelain samples and dose-evaluation of nuclear-energy related accident using ceramics materials.
