Testing of acoustic cameras to detect leakage through a concrete structure
The acoustic cameras were tested by personnel from Ringhals NPP with earlier experience from using acoustic camera during containment leak rate test. The main result is that you should not relay entirely on the camera. A combination of camera and leak spray is recommended.
