摘要
本文介绍了重离子束的基本特性和在生命科学应用中的优势,以及它的能区划分,传能线密度LET,相对生物效率RBE等,分别叙述了中、高能和低能离子束与介质作用的特点、在农学中应用的模式及其吸收剂量的计算,最后还对一些机理问题进行了简单讨论.
Abstract
Essential characteristic, divided energy region, linear energy transfer (LET), relative biological effectiveness (RBE) of heavy ion beams and their superiority applied in life sciences are introduced in the paper. The features of effect of ion beams with middle, high and low energy on media, irradiation modes used in agriculture and calculation of absorbed dose is described respectively. Finally, some mechanisms are briefly discussed.
