目的:探讨纳米铁核素应用于内照射治疗的两种常用方式,以及两种方式下放射性纳米铁在体内的剂量行为.方法:选取衰变时发射B射线的纳米铁核素,分别经动脉注入肝脏和经皮穿刺瘤内直接注射人肝脏.结果:纳米铁核素能对肝组织产生较大的辐射.结论:其肝组织的吸收剂量要根据其采用的治疗方式,使用不同的估算方法.

Objective ：To study the two common method of internal irradiation for nanometer-iron nuclide, and how to estimation of the absorbed dose for each of them. Methods： We chose the nanometer-iron nuclide emitting β-ray during the decay period, Respectively, Arterial injected into the liver or percutaneous puncture direct inject into the liver. Results： Through the formula, a few nanometer-iron nuclide can produced greater radiation. Conclusion： The es...
