Not that what you are saying is not true, but the bulk of fluoride contaminating the environment came about much earlier than the atom bomb. Fluoride started out as an industrial byproduct of aluminum manufacturing in the early twentieth century. It was correctly classified as a toxic compound and pressure was being exerted on aluminum companies in the 1920s and 1930's to clean up the water supplies. These companies were dumping fluoride into the water by the tons unrestricted. Magically, through some bribed bogus epidemiological studies, arm twisting at the AMA, and the newly created department of US Public Health Service formed under FDR's new deal, almost overnight fluoride went from being a toxin slated to be removed from our nation's waterways to something good for health - all with no real scientific data to back it up. The toxic waste was now sold to the public as a means to prevent tooth decay. The cover story surrounding fluoride was already well under way by the time Manhattan took its turn at polluting the environment.

Look up the links concerning Alcoa Aluminum and its connections to FDR's administration. It the same old corruption dance we still see concerning corporate oligarchy. Most of the sodium fluoride sourcing today comes from fertilizer manufacturing. It was sold as a new and improved fluoride versus the older version derived from aluminum manufacturing - although the earlier form it is still available in some toothpastes like the original Crest.
