摘要：A method of and apparatus for obtaining radiation transmission data andespecially an image of an object which involves providing a radiation source such as an x-ray or gamma-ray source and a radiation detector system such as an x-ray or gamma-raydetection system spaced therefrom to define a scanning zone therebetween, thedetector system being capable of detecting and collecting spectroscopically resolvableinformation about incident radiation; collecting a dataset of information aboutradiationincident at the detector and hence transmissivity of an object in the scanningzone at at least one and preferably a plurality of scanning positions from radiationtransmitted through the object and received at the detector system; resolving each suchdataset spectroscopically across a plurality of frequency bands within the spectrum ofthe source; wherein at least one of the said plurality of frequency bands corresponds to acharacteristically scattered wavelength of a target species to be identified, andwhereinthe absence of or substantial reduction in a transmitted signal intensity at the frequency
band is interpreted as the presence of the said target species. The resolved data ispreferably resolved as one or more images.
