摘　　要：本文介绍用核磁共振谱仪、双波长薄层色谱扫描仪测含Fe^(2+)水凝胶体系中的吸收剂量分布。结果表明,在剂量低于16Gy时,琼酯糖胶体中质子弛豫速率与剂量呈良好的线性关系,用丙烯酰胺薄膜代替胶片剂量计测剂量均匀度曲线具有明显的优点。By the aid of nuclear magnetic resonance and dual wavelength TLC scanner, the absorbed dose distribution in hydrogels containing ferrous sulfate has been measured. The result shows a good straight line between the proton longitudinal relaxation rate and absorbed dose up to 16Gy in agarose gels. It appeared that thin layer of acrylamide is much better than film for obtaining smooth dose curves.
