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.
