From the article: "if the black hole’s temperature is high, the radiation is composed of all elementary particles, photons, electrons, quarks, and so on. It’s really unhealthy. And a small black hole converts energy into a lot of those particles very quickly. This means a small black hole is black basically a bomb." The nuclear waste thrown into it may be much cleaner than the stuff it will throw back out.
