I am not sure if there were any ships from the bikini atoll testing at Treasure Island, or not. Very well could have been though. I was the Lead HP supervisor at Hunters Point shipyard from 2003-2005, and was involved with the site historical assessment for Hunters Point. I do know that there are records of some of the ships being decontaminated there, at Hunters Point. Treasure Island is right around the corner, so it is very possible. Also, Hunters Point was at one time the a main hub for the Navy’s nuclear research. Various animal testing..ect. There was also a lot of research done at Hunters Point on various samples from nuke testing in the desert, which could have carried over to treasure Island. Aside from loads of radium, from dials, paint booths..ect. Honestly, who really knows what all they did in those bay area naval bases……The navy / RASO is very good at not having a record of something, until you just happen to run across some sort of an anomaly, then they all of the sudden remember and have some process knowledge , or actual records.
