A few of roof the pieces were subjected to therrnoluminescence TL –dating. Two ages estimated from these RTL-accumulated doses and annual doses gave an excellent agreement with the predicted age, although one sample showed different behavior of RTL-glowcurves depending on kinds and energies of radiation, resulted in finally scattering age. Additionally, every ages evaluated from feldspar fractions offered relatively young ages even using far-RTL measurements, as well as BTL-ones. As a result, BTL from feldspar fractions possessed high sensitivity, giving highest one from orthoclase, whereas RTL from quartz and far-RTL from feldspar fractions indicated extremely weak sensitivity, amounting to three order faint intensity. Finally, it was concluded that contamination of feldspar into quartz fraction will be negligibly small contribution in the case of RTL-measurement, while such feldspar-contaminated quartz fraction will cause erroneous result in the case of BTL-dosimetry.

Pantiles on the other hand only required 1 to 2 thicknesses at any point. It is for this reason that we refer nowadays to plain tiles as “double lap tiles”, but we call tiles which overlap or interlock with each other “single lap tiles”. To construct a roof using plain tiles you need 60 tiles per square metre, but if you use pantiles you only need about 15 tiles.
An article exploring clay-tiled roofs and their history, as well as the manufacturing From the 17th century clay tile became the ubiquitous roofing material for large parts of the tiles means the tiles cannot be salvaged for re-use at a later date.
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. 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. This is a preview of subscription content, log in to check access. Rent this article via DeepDyve. Hashimoto, H. Fujita, K. Yasuda , Radioisotopes, 48 Google Scholar. Fattahi, S.
