| 摘 要： | 将类丁二炔化合物自组装成纳米囊泡后,均匀分散于凝胶载体中,研制出一种新型的辐射变色凝胶剂量计。用电镜观测了囊泡形貌,采用CL-1000型紫外交联仪对凝胶进行辐照,测试并研究了凝胶对紫外辐照的变色响应、辐射后效应、扩散效应等剂量学性能。结果表明:该辐射变色凝胶在5~150mJ/cm2能量密度范围内对紫外线辐照具有良好的响应线性,同时克服了扩散效应、辐射后效应、成型能力差等现有凝胶剂量计的不足。该辐射变色凝胶剂量计适于光学扫描方式测量剂量分布。

UV irradiation effect on a new radiochromic gel |
| |
| Abstract: | A novel radiochromic gel dosimeter was developed through dispersing nanovesicles self-assembled by diacetylene into the gel matrix. The vesicle morphology was observed through electron microscopy; The radiochromic gels were irradiated by CL-1000 UV crosslinker and their dosimetry performance was tested and studied. Results indicate that these radiochromic gels have good linear response to UV irradiation in the energy density range of 5~150 mJ/cm2. In addition, the radiochromic gels overcome the limitations of the existing gel dosimeter such as diffusion effect, post-radiation effect, and poor forming ability. Hence, the radiochromic diacetylene vesicle gel dosimeters developed could be generally applied to 3D dose distribution measurement with optical readout. |
