1. A system for detection and imaging of nuclear-radiological threats and benign radiation from a screened object, comprising:

  • at least one nuclear imager adapted to image spontaneous radiation from within an object; and

    at least one camera that images a field of view of said imager from outside the object to form at least one optical image; and

    a controller that receives the at least one nuclear radiation image and the at least one optical image of the outside of the screened object and determines a distribution of sources of radiation within the screened object, correlates the position of the distribution with the optical image and indicates a possible threat based on loci of the radiation source within the screened object.
