chill in compacted-graphite cast-iron

I have cylindrical castings of compacted-graphite cast-iron (CGI, or DIN-EN GJV) and a big batch (2000 pcs) are 'contaminated' with white-chill at the inner diameter. The inner diameter is not machined but as-cast (centrifucal casting method) with moreless irregular skin.

Is there a NDT method that can sort out good/bad parts? Penetration depth ranges from 0 to several mm. Limit is 2mm.

Anyone who can give me some references / applications where NDT was helpful? Please, only references with cast-iron. Steel does not help.
