引言热释光剂量测量方法是近十几年来迅速发展起来的一种新型剂量监测技术。由于它具有许多优点,在辐射防护、放射医学与放射生物学、地质、考古等方面都备受重视,并得到广泛应用。在热释光测量技术中,粉末状热释光材料具有分散性小,测量中不需要进行挑选等优点。因此,在热释光测量工作中,粉末状热释光材料至今仍是人们喜欢的重要探测元件。但是,它与成形的热释光元件相比,使用粉末也有某些不便之处。例如,为保证剂量测定的精度要求对成千上万份热释光粉末要准确称量。
Introduction The thermoluminescence dose measurement method is a new type of dose monitoring technique developed rapidly in recent ten years. Because of its many advantages, it has received much attention in radiation protection, radiation medicine and radiobiology, geology and archeology, and has been widely used. In the thermoluminescence measurement technology, the powdery thermoluminescent material has the advantages of small dispersion, no need to select in the measurement, and the like. Therefore, in the thermoluminescence measurement, powdered thermoluminescent material is still an important detection element that people like today. However, it also has some inconveniences of using the powder as compared with the shaped thermoluminescent element. For example, thousands of parts of thermoluminescent powder must be accurately weighed to ensure the accuracy of dosimetry.
