随着原子能事业的发展,特别是同位素和核射线在医学领域中广泛地应用,辐射的危害日益引起人们的关注。在医疗照射中,既要获得理想的诊治效果,又要保障工作人员和患者的辐照安全,即如何实现医疗照射的最优化,剂量测量的规范化,已是放射医学、辐射剂量学的重要课题。辐照体模(Phantom)是用与活的人体组织对射线散射和吸收相似的多种高分子材料制
With the development of atomic energy, especially isotopes and nuclear rays widely used in the field of medicine, the harm of radiation is attracting more and more attention. In the medical irradiation, it is necessary to obtain the ideal diagnosis and treatment effect, but also to protect the radiation safety of staff and patients, that is how to optimize the medical irradiation, the standardization of dose measurement, radiation medicine has become an important issue of radiation dosimetry . Phantom is a kind of phantom that is made of many kinds of macromolecule material similar to living body tissue for radiation scattering and absorption
