    摘要: The invention relates to a method for sorting, in a continuous flow, contaminated materials (100), which includes: conveying materials (100) from a point (A) to a point (B) by means of a conveyor (120); measuring the radioactive activity, by means of a first sensor (140), between the points (A) and (B) on the top surface (FSUP) of the first conveyor (120); and sorting the materials (100) by means of a sorting device (130). Said method is essentially characterized by: measuring the radioactive activity of the contaminated material by means of a second sensor (141), either on the top surface (FSUP) of the conveyor (120) and upstream from the point (A), or below the bottom surface (FINF) of said conveyor; calculating a differential measurement between a measurement from the second sensor (141) and from the first sensor (140); and restricting the sorting to the comparison between a threshold value and the measurement from the first sensor (140) or the differential measurement.
