In order to distinguish it from the movement caused by the turbulence of the transportation vehicle, this paper proposes the criterion of "illegal movement" as the movement of radioactive materials outside the transportation compartment. Since the interior of the compartment is generally a metal environment, this paper proposes wireless signal strength data as a sensing method. The wireless signal strength data is filtered and converted into distance data. We construct a spatial triangle perpendi...
