随着热发光机制的研究及辐射剂量学的发展,热发光技术近年来已有效地应用于核物理、放射医学、地质、考古等方面,并在地质、考古年龄测定中取得了一定的进展。根据热发光测定年龄原理,燃烧烘烤后的沉积物辐射剂量从零开始累积。累积量与时间成正比,因而用热发光方法测定地质年龄是行之有效的。我们对周口店“北京人”遗址第一地点上、下文化层的灰烬物质及第四地点灰烬物质用石英包体法进行了热发光测定年龄。其结果分别为29万年(上文
With the research of thermoluminescence mechanism and the development of radiation dosimetry, the thermoluminescence technology has been effectively applied to nuclear physics, radiology, geology and archeology in recent years. Some progress has been made in the determination of geology and archeology. According to the principle of thermoluminescence determination of age, the radiation dose of the burnt deposit accumulated from zero. Cumulative amount is proportional to time, so using geoluminescence method to determine the geologic age is effective. We conducted a thermoluminescence dating of the ash and ash contents of the upper and lower cultural layers of the Beijingerites site in the Zhoukoudian site and the quartz inclusions in the fourth site. The results were 29 million years (above
