I stay now for a few months in Poland, working on a project on NORM in
drinking water. Because of numerous discussions inspired by the fact that
the European Union set only a radiation specific limit for radionuclides
including "uranium", though uranium is far more chemotoxic than radiotoxic I
wonder, how the situation is with thorium. I have not found anything useful
about chemotoxicity of thorium in comparison of its (high) radiotoxicity.
Any information, any links available?

Best regards,
