Some Cr compounds are, some aren't. So called "hexavalent chromium" or Cr(+6) compounds are toxic and carcinogenic. They're a common form of industrial pollution since all of the methods used to refine chromium create Cr(+6) as an intermediate product before finally converting it into metallic chrome. Cr(+6) was used for chrome plating in the past, and still is today. But it's being replaced by "trivalent chrome plating" which is more efficient, less dangerous, and far less polluting.

@shidoink I looked it up. The tests are not definitive: the animals developed cancer when the cobalt was placed directly against the muscle under the skin, but didn't get it from eating, drinking or breathing it. Just touching it won't give you cancer.

you just said it all... it's no different from regular cobalt it's just radioactive... every element has a radioactive isotope the one with the most stable isotopes is tin which has 10 stable isotopes.
