nanogenerators (Score 2, Insightful)

I think that this is a very interesting venue in the treatment of cancer. Even though the radioactive atom "eventually becomes harmless and remains in the body," I still think it highly possible that this treatment may be nullified by the radiation emitted by the nanogenerators. Hopefully this is not the case, and we will have found an effective and non-harmful (minimally so, at least) treatment for cancer.
