It is a successful method to use radioisotope tracer technique for detecting the leakage of a dam. We have applied
131
I as the tracer in many boreholes around Nanfu dam of Haizi reservoir in Beijing
to detect the leakage. The isotope tracer flow meters had been used to detect the direction and velocity of underground water flow in the boreholes at the depths of 20—90 meters
A main leakage passageway under the dam was confirmed by the detection
thus providing a scientific basis for reinforcing the dam.
