Gel dosimetry has been studied mainly for medical applications. The radiation induced ferric ions concentration can be measured by different techniques to be related with the absorbed dose. Aiming to assess gamma/thermal neutrons dose from research reactors, Fricke gel and alanine gel solutions produced at IPEN using 300 bloom gelatin were mixed with Na(2)B(4)O(7) salt, and the mixtures were irradiated at the beam hole #3 of the IEA-R1 research reactor, (BH#3) adapted to BNCT studies, and the dose-response was evaluated using spectrophotometry technique.
凝胶剂量学主要针对医学应用进行了研究。辐射诱导的铁离子浓度可通过不同技术进行测量，以与吸收剂量相关联。为了评估研究堆产生的伽马/热中子剂量，在IPEN使用300勃氏明胶制备的弗里克凝胶和丙氨酸凝胶溶液与硼砂盐混合，并将混合物在IEA-R1研究堆的第3号束孔（BH#3，适用于硼中子俘获治疗研究）进行辐照，然后使用分光光度法技术评估剂量响应。
