According to the aerogeophysical integrated survey carried out in the Yellow River mouth area of Shandong Province,this paper describes the application of airborne gamma spectral data to the evaluation of environmental radiation level and the delineation of the limits of radioactive pollution.It is pointed out that,although the background radiation level of this area is relatively low,a number of radioactive anomalies detected within the area constitute an environmental problem which deserves our serious attention.
