The former San Bruno Navy Base which is currently the site of YouTube Headquarters was irradiated with Radio-Tantalum which decays into Radio Tungsten and so the people who work there are subject to alpha contamination to this day!. I highly recommend YouTube and Walmart leave this site and not build on a toxic waste site. Google Headquarters is located on an EPA Superfund site and I recommend they leave the property as fast as they can. How can you hire people to work on an EPA superfund site knowing it is a toxic waste site? Do the employees know?

The following are references and chronologies of the Navy’s testing where they purposely contaminated areas to radiation levels of between 1000 and 10,000 rads to simulate the effect of an atomic bomb blast and how they cleaned up the area. The problem here is that the dose rates reported are of the clean up crews, but there are people who set up these situations, spreading the contaminated material onto the streets, buildings and yards. What happened to them?
Operation Supersweep is still classified, probably for the exact reasons written above. Spreading radioactive contaminates directly onto grounds is not good for real estate values.
