The silicon photomultiplier (SiPM) can be used to detect radiation when coupled to a scintillator. A SiPM is low-level light sensitive device which generates current from an incident photon. The ability to shape a 3d-printed scintillator to couple with any SiPM while maintaining a portable form factor offers great flexibility to radiation detectors. Results indicate that SiPMs can successfully detect radiation with 3d-printed scintillators. Pulse shape discrimination methods (such as charge-integration) can be used to discriminate between neutron and gamma/beta radiation in both commercial and 3d-printed scintillators. Current research focuses on increasing the portability of the detector.
