Abstract
A radiation detector includes a printed circuit board and a detector assembly operably connected to the printed circuit board. The detector assembly includes a silicon photomultiplier and an organic scintillator coating applied to a surface of the silicon photomultiplier. A reflective foil covers the organic scintillator coating. A light sealing cover is secured to the printed circuit board such that the silicon photomultiplier and the organic scintillator are encapsulated within the light sealing cover.

A radiation detector comprising:
- a printed circuit board;
- and
- a detector assembly operably connected to the printed circuit board and comprising:
- a silicon photomultiplier;
- an organic scintillator coating applied to a surface of the silicon photomultiplier;
- at least one layer of varnish on a surface of the scintillator;
- a reflective foil covering the varnish and organic scintillator coating, wherein the reflective foil, the varnish, and the organic scintillator are adhered together without an air gap;
- and
- a light sealing cover secured to an upper surface of the printed circuit board about a periphery of the detector assembly.
A method of manufacturing a radiation detector comprising the steps of:
- combining an organic scintillator and a solvent in a pipette;
- dispensing the organic scintillator and solvent onto a surface of a silicon photomultiplier positioned on a printed circuit board;
- drying the organic scintillator and silicon photomultiplier on the printed circuit board such that the solvent evaporates;
- coating a surface of the organic scintillator with at least one layer of varnish;
- and
- applying an optical reflector on the organic scintillator, wherein the reflective foil, the varnish, and the organic scintillator are adhered together without an air gap.
