Puerto Rico, at this moment has registered 227 licenses before the Nuclear Regulatory Commission. Nor the scientific community, nether the academic and forget the local government of Puerto Rico - placed attention, to the management and current amount of nuclear waste and its disposal around the Island. Currently many hospitals and universities are in non-compliance and violation of the law. NRC licenses the following activities: * possession, use, processing, exporting, importing, and certain aspects of transporting nuclear materials and waste (See: http://www.nrc.gov/about-nrc/regulatory/licensing.html ) The general public and local communities are not even aware of the potential - disasters in the making. It’s just a matter of time Personally, I prefer the most restrictive environmental safeguard, regardless of what jurisdiction the source is. But the Puerto Rican Government is not even an Associate with the NRC, which just requires a letter from the Governor. Something to consider and think about in a broader spectrum: "In the United States there are large quantities of nonfissionable but highly radioactive materials contained within machines, primarily in hospitals and at industrial sites, and the machines, because they are expensive, are sometimes stolen for resale. In fact in the United States alone there are hundreds of thefts of radioactive material every year. As to why no dirty bomb has yet been assembled and used, analysts provide earnest explanations, but largely to avoid throwing up their hands in wonder. It turns out that the world is rich with fresh, safe, user-friendly Highly Enriched Uranium -- a global accumulation (outside of our collective thirty thousand nuclear warheads) that is dispersed among hundreds of sites and further separated into nicely transportable, necessarily subcritical packages. The practical question is how to pick some up." -- The Atomic Bazaar: The Rise of the Nuclear Poor, William Langewiesche, 2007, pp. 18, 27.
