Feasibility Study on Preparation of Photosensitive Resin for 137Cs 3D Printing by Phase Transfer Method

Abstract

To introduce 3D printing technology into the field of radiation source preparation and make up for the lack of precision special-shaped radiation source preparation technology at home and abroad. The photosensitive resin for 133Cs 3D printing was prepared by studying the phase transfer method and detected by ICP-MS to explore the preparation conditions. Then, the photosensitive resin material for 137Cs 3D printing was prepared and detected by lanthanum bromide detector. The results show that the uneven distribution of cesium in three photosensitive resins for 133Cs 3D printing and 137Cs 3D printing prepared by phase transfer method was less than 5%. As a simple and mild method, phase transfer method can be used to prepare photosensitive resin for 3D printing containing cesium, and has certain universality.
