Absolutely correct about insoluble barium compounds being used for x-rays,
i'm not sure about current practice, but they used to use the sulphate which
is virtually insoluble. Barium titanate is also insoluble, so of relatively
low toxicity, but inhaled dust is extremely hazardous, so don't blow them up
or do anything silly with them, mind you if one blew up I suspect the
potential of blast injury would outweigh the toxicity risk.
