摘要
Abstract
This research investigates the utilization of 3D printing technology and the phase transfer method to fabricate photosensitive resin containing the radionuclide 131I,aiming to simulate the neck-thyroid source model for the efficiency calibration of detectors.Through optimizing the type,dosage,mixing time of the phase transfer agent,as well as the addition amount of 131I,a well-uniform 131I photosensitive resin was successfully prepared.By means of 3D printing technology,the thyroid source model was fabricated and a comparative measurement was conducted with the IAEA(International Atomic Energy Agency)/ANSI(American National Standards Institute)neck phantom.The experimental results indicate that the detection efficiency of the thyroid source model prepared using 131I photosensitive resin is in line with that of the IAEA/ANSI neck phantom,proving the feasibility of 3D printing technology and phase transfer method for preparing photosensitive resin thyroid body source and offering a novel approach for the preparation of other complex heterogeneous source models.关键词
