Sixty three porcelain shards and four brick and tile samples unearthed from the Qinglong Town Archaeological Site in Shanghai were studied in this research. The thermoluminescence (TL) pre-dose technique was applied to acquire the paleo-dose of porcelain samples. The fine grain technique was applied to acquire the paleo-dose of brick and tile samples. The thick source α-counting method and X-ray fluorescence (XRF) spectrometry were used to acquire the annual dose of the samples. The TL dating results indicate that the porcelain samples were from the Tang Dynasty to the Southern Song Dynasty. The brick and tile samples dated back to the Northern Song Dynasty, which is consistent with what was recorded in the historical literature about the first construction years of the Longping Temple Pagoda.
