摘要：
A method for sorting, in a continuous flow, contaminated materials, which includes: conveying materials from a point (A) to a point (B) by means of a conveyor; measuring the radioactive activity by means of a first sensor between the points (A) and (B) on the top surface (FSUP) of the first conveyor; and sorting the materials by means of a sorting device. The method may include measuring the radioactive activity of the contaminated material by means of a second sensor, either on the top surface (FSUP) of the conveyor 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 and from the first sensor; and restricting the sorting to the comparison between a threshold value and the measurement from the first sensor or the differential measurement.
