1. A digital quantum dot radiographic detection system comprising:
(a) a scintillation subsystem that converts ionizing radiation into light, said scintillation subsystem having a plurality of discrete scintillation packets;
(b) a semiconductor light detection subsystem having a plurality of quantum dot image sensors, said quantum dot image sensors detecting said light from said scintillation subsystem and converting said light into at least one electronic signal; and
(c) an optically opaque layer being positioned between said discrete scintillation packets.
