用热释光(简称TL)方法测定古代陶器的烧制年代是近十几年发展起来的一项考古新技术。TL测定年代的原理是根据陶器烧成后,器物中石英和长石等晶体所吸收的自然辐照累积剂量来计算年代的,实际计算年代的公式为: A=(D_e+△)/(εR_a+R_β+R_γ+R_c)式中,D_c为等效β剂量;△是TL对自然辐射剂量的超线性修正值;ε为α对β的相对发光效率;R_α、R_β、R_γ、R_c分别为α、β、γ和宇宙射线年剂量。 我们用实验室装置的热释光测量仪对许多陶器和砖瓦标本进行了测定,其制样方法和实验步骤见文
The determination of the burning time of ancient pottery by the method of TL (TL) is a new archeology developed in recent ten years. The principle of TL dating is based on the cumulative dose of natural radiation absorbed by crystals such as quartz and feldspar after firing of pottery to calculate the age. The formula for the actual calculation is: A = (D_e + Δ) / (εR_a + R_β + R_γ + R_c) where D_c is the equivalent beta dose; Δ is the superlinear correction value of TL for the natural radiation dose; ε is the relative luminescence efficiency of α to β; R_α, R_β, R_γ and R_c are respectively α, β, γ and cosmic rays annual dose. We measured many pottery and tile specimens using a lab-based thermoluminescence meter, and the sample preparation method and experimental procedure are described in
