摘要

丙氨酸剂量计作为固体剂量计被广泛使用，但由于其对低剂量的灵敏度较低，因此很难评估毫戈瑞量级的辐射剂量。我们应用电子自旋共振剂量测定技术研究了羟基磷灰石（牙齿的主要成分）是否适合作为新型剂量计的材料，以检测从 mGy 到 Gy 的辐射。市场上出售的合成羟基磷灰石具有剂量计材料所需的基本特征，并已证明可以准确测量 mGy 至 Gy 范围内的剂量。

Evaluation of materials for developing a new individual dosemeter using electron spin resonance spectroscopy.

Alanine dosemeters are widely used as solid dosemeters; however, evaluating doses in the mGy order of radiation is difficult because of their lower sensitivity for low doses. We applied the electron spin resonance dosimetry technique to investigate whether hydroxyapatite, the main component of teeth, is a suitable material for a new dosemeter to detect radiation from mGy to Gy. Commercially available synthetic hydroxyapatite possesses the essential characteristics required for a dosemeter material and has been demonstrated to accurately measure doses in the mGy to Gy range.

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
