A thorax phantom has been designed, consisting of PMMA and PE plates containing a cavity filled with a laboratory-made lung-substitute. Fricke-gel dosimeters have been placed in the lung-substitute volume, and the phantom has been irradiated at the epithermal column of LVR-15 reactor. Absorbed dose images have been obtained for both gamma radiation and charged particles emitted in the (10)B reactions with thermal neutrons. Measurements with thermoluminescence dosimeters (TLDs) and Monte Carlo (MC) calculations have been performed too, in order to attain inter-comparison of results.
设计了一种胸部体模，它由聚甲基丙烯酸甲酯（PMMA）和聚乙烯（PE）板组成，其中包含一个填充有实验室自制肺替代物的腔体。弗里克凝胶剂量计已放置在肺替代物区域内，并且该体模已在LVR - 15反应堆的超热柱处进行了辐照。已获得γ辐射以及硼 - 10与热中子反应中发射的带电粒子的吸收剂量图像。为了实现结果的相互比较，还进行了热释光剂量计（TLD）测量和蒙特卡罗（MC）计算。
