Claim One:
1. A method for detecting radioactive emissions in a radiation monitoring station. the method comprising: acquiring a first radiation measurement from a moving radiological source over a first field of view in the radiation monitoring station: acquiring a second radiation measurement from the moving radiological source over a second field of view in the radiation monitoring station, wherein at least a portion of the second field of view is substantially distinct from the first field of view and a transition zone is established between at least a portion of the first field of view and the second field of view; calculating a dependent variable of a function defined at least in part by the first radiation level measurement and the second radiation level measurement: determining when the dependent variable reaches a first threshold value as the moving radiological source moves through the transition zone: and triggering a detection alert when the dependent variable reaches the first threshold value.
