Beschreibung
Zusammenfassung:	The invention discloses a radioactive source tracking and positioning method and system. The method comprises the following steps: 1) selecting a measurement point; 2) selecting a plurality of sampling points within the distance range of the sampling step length of the measuring points; 3) respectively measuring the radiation intensity at the measuring point and the sampling point; 4) determining the radiation intensity gradient of the measuring point according to the radiation intensity of the measuring point and the radiation intensity of the sampling point; 5) selecting a next measurement point according to the distance of the measurement step length along the reverse direction of the radiation intensity gradient at the measurement point; and 6) repeating the steps 1)-5) until the radioactive source is found. The method comprises the following steps: gradually searching a radioactive source along the reverse direction of the gradient, selecting a measurement point, sampling around the measurement point, ca
