Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the State Administration of Cultural Heritage. This standard is under the jurisdiction of the National Cultural Relics Protection Standardization Technical Committee (SAC/TC289). This standard was drafted. Shanghai Museum. The main drafters of this standard. Xia Junding, Wu Hao, Wang Weida, Xiong Yingfei, Gong Yuwu. Ancient ceramic thermoluminescence measurement technology specification

1 Scope

This standard specifies the terminology and definition of the age of ancient ceramic thermoluminescence measurement, ancient dose measurement of ceramics, ancient dose measurement of porcelain, annual dose Measurement and calculation, calibration of laboratory radioactive sources, errors in the measurement of ancient ceramic thermoluminescence, and data processing and reporting. This standard applies to ancient ceramic thermoluminescence dating and authenticity identification.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Pottery pottery The clay is used as the main raw material, and after being subjected to processes such as molding and drying, it is fired at a temperature of about 800 ° C to 1150 ° C. 2.2 Porcelain porcelain Using one or more silicon-rich natural minerals as raw materials, after the process of compounding, forming, drying, etc., the surface is glazed or not glazed, in the kiln The inside is fired at a temperature of about 1150 ° C to 1350 ° C. 2.3 Phosphor phosphor A mineral crystal such as quartz having a light-emitting property. 2.4 Thermoluminescence dating The phenomenon that the radiant energy accumulated in the phosphor is converted into light energy by heating to determine the last time the ceramic sample is heated to the measurement The time passed. 2.5 Cumulative dose accumulateddose The natural irradiation dose absorbed by the ceramic sample from the last heat to the measurement. 2.6 Equivalent beta dose equivalentbetadose Qβ Equivalent to the natural cumulative dose of the unit beta dose. 2.7 Equivalent alpha dose equivalentalphadose Qα Equivalent to the natural cumulative dose of unit alpha dose. 2.8 Environmental dose environmentdose γ c It consists of gamma rays and cosmic rays c in the soil of the buried objects, and together provides a radioactive dose to the ceramic samples. ......
