I'm pretty sure that's not what they meant, but maybe...

Radionuclides are present in coal fly ash because they are present in
coal.

Why stop using it, when you can just test it?  Get a geiger counter,
check the concrete as it arrives.  If it exceeds whatever standard you
decide on, send it back.  Concrete company won't have many returned
trucks before they make sure that it doesn't happen.  Then we all
benefit (shorter feedback cycle is always an improvement IMHO).

Thank You Kindly,
