| Abstract Scope |
In this project we design and build a plastic scintillation detector using additive manufacturing for use in detecting ionizing radiation with the intent being to create a small unobtrusive wearable dosimeter. An off the shelf stereolithography printer was used with standard resin which was then doped with varying amounts anthracene as the scintillating medium. The concentration of the dopant, method of mixing, and overall process was determined to produce a part which was mated with a standard photomultiplier tube producing an additively manufactured plastic scintillator. The overall detector was tested with medium to high energy gamma sources over short exposure periods clearly distinguishing the sources from background with a continuum response at low energies relative to the strength and energy of the source. Future work includes customization of geometry, coupling to other sensors, expansion to other printing methods, and evaluation of non-ionizing radiation solutions to create a discreet wearable dosimeter. |
