The invention relates to a radionuclide distribution mapping system. Comprising an unmanned aerial vehicle carrying a gamma spectrometer, and further comprises a path planning module, a gamma spectrometer measurement module, an inversion drawing module and a visualization and communication module. The invention further relates to a drawing method. Comprising the following steps: step 1, an operator plans a route of an unmanned aerial vehicle according to a to-be-measured area, and injects measurement waypoint information into the unmanned aerial vehicle; 2, the unmanned aerial vehicle flies along a set route, and when the unmanned aerial vehicle reaches a set measurement waypoint position, a carried gamma spectrometer carries out radioactivity detection to obtain detection data; 3, constructing an energy spectrum according to the obtained detection data, calculating to obtain full-energy peak counting rate data, activity data and dose rate data, and estimating the category of radionuclides; and step 4, performing inversion drawing according to the obtained calculation data to obtain a distribution map of the radionuclide feature information. According to the method, the drawing precision is improved, the application range is expanded, the drawing cost is reduced, and the time required for emergency response is shortened.
