摘要： A detector apparatus (10) is provided and includes a collector (20) having access to a sample of a gaseous fluid and a tester (40) coupled to and disposed remotely from the collector (20). The tester (40) includes a test chamber (41) into which a sample is directed from the collector (20), an excitation element 43, such as a laser, to excite the sample in the test chamber (41) and a spectrum analyzing device (44), such as a spectrometer, coupled to the test chamber (41) to analyze the excited sample, and preferably to generate a plasma or filament, for evidence of a concentration of particles of interest, such as isotopic molecules, in the gaseous fluid exceeding a threshold concentration. The threshold concentration is defined in accordance with a type of the particles of interest and a residence time of the sample. In particular, the apparatus is for radioactive anomaly detection of hidden or shielded special nuclear materials (SNM) or smuggled nuclear weapons in shipping containers at ports where the are loaded or unloaded via a crane system, or at check points when the containers are on trucks that move or pass through check points.
