Abstract

The invention provides a radioactive source positioning method and electronic equipment, and the method comprises the steps: obtaining the measurement data of each measurement point measured by measurement equipment; determining an initial value of a radiation parameter in the relation equation function; wherein the relation equation function is used for representing a relation among the dose rate of the measurement point, the radiation parameter and the coordinate of the measurement point; inputting the initial value of the radiation parameter and the coordinate of each measurement point into the relation equation function to obtain the predicted dose rate of each measurement point; based on the dose rate loss value of the predicted dose rate of each measurement point relative to the actual dose rate, using the partial derivative function of the relation equation function to adjust the radiation parameter, and iterating until the relation equation function meets the convergence condition; and taking the radioactive source coordinate under the condition that the relation equation function meets the convergence condition as a target radioactive source coordinate. According to the technical scheme of the embodiment of the invention, the coordinates of the target radioactive source can be quickly and accurately determined by using a nonlinear fitting method.
