The microdosimetric spectrum and radial dose distribution of 16 O + particles with energy 109 keV generated from small low energy heavy ion accelerator permeating through PET film (C 10 H 8O 4) with thickness of 4 μm are measured by the cylindrical tissue equivalent proportional counter.
用圆柱型流气式组织等效正比计数器测定了K 2 0 0kV低能重离子加速器提供的低能16O+离子束流在穿过 4μm厚的PET(C10 H8O4 )薄膜后的微剂量谱和径向剂量分布。
Based on our Month Carlo Calculation model of heavy ion track structure,the radial dose distribution around an energetic heavy ion path and the maximum radial effect range in the liquid water are calculated.
根据建立的重离子径迹结构ＭｏｎｔｅＣａｒｌｏ计算模型，计算了重离子在液态水介质中的径向剂量分布和最大作用范围，计算结果同实验或其它δ射线理论计算值进行了比较，其目的在于建立细胞损伤强度和损伤范围与重离子参量之间的关系，从理论上探索重离子生物效应的机理。
