Navy denial of radiation on Treasure Island – the paper trail of the lie

The Navy has denied that any radiological activity took place on Treasure Island even when they have found 60 Rems per year of Radium from the top 10 inches of soil under the public housing on the site and just recently in May 2021 they found another 30 REMS per year of nuclear radiation under the public housing on the site. They originally made these claims while the Radiological School was still in operation on the Island, so there is no excuse, THEY LIED and the politicians have used this lie to perpetrate a fraud on the people of San Francisco, leaving them holding the bag for the cleanup.!

This report resides in multiple PDF files on the Envirostor Database and so there will be many links and it is the denial that was used to whitewash the 1995 report to deny any radiological activity but in the fine print it says the direct opposite, citing dumping of radioactive waste on the site where two examples are listed below and other references to the radiation can be found using a simple search of the documents.

The Paper Trail – the following is a list of people and their correspondence who made the false statement in the report that here was no radioactive materials buried on the island.

“Radioactive Materials/Mixed Wastes. File information was reviewed to identify parcels where radioactive materials/mixed wastes were stored and the period of time they were stored. EFA WEST also provided information to ERM-West regarding radiological activities for all of the parcels on Treasure and Yerba Buena Islands. This information was obtained through the Naval Sea Systems Command Detachment, Radiological Affairs Support Office (RASO). A description of the material was included in the database.”

This is the letter that DTSC uses to claim no radiation at the site. This paragraph is in reference to a chart of each building and areas defined in the map (above) found at the beginning of the document that broke up Treasure Island into 120 separate areas and another 26 on YBI and this chart has no indication of radiation, no checkmarks in the radiation tab for each site. Why would they have it as an item if there are no checkmarks on it anywhere unless the report was censored?

There are other references to the USS Pandemonium and radiological training on Treasure Island in this overall baseline report. Again I want to emphasize that the reports conclusions do not match up with the content in the document.

Note T102 is the location of the first USS Pandemonium where they lost the Radium Needles and Radium materials (see below)

“Radioactive Materials/Mixed Wastes.  A check mark indicates that radioactive materials or mixed wastes are currently or were formerly used, stored, or disposed of on the parcel. This condition may preclude a parcel from being considered for CERFA-eligibility. Radiological issues were of particular concern to regulatory agencies for BRAC classification. Therefore, in addition to the review of on-site records, EFA WEST requested that RASO search for information on known and potential uses of radioactive materials at the base. RASO concurrence is required prior to nomination for CERFA, for lease, or for transfer. In a March 8, 1995, letter from Lt. Commander Heron of EFA WEST, to Mr. David Wang of DTSC, RASO concluded that there is no potential for residual contamination at NAVSTA TI (NSTI) as a result of licensed activities and no radioactive materials were disposed of on site. This conclusion from RASO applies to all parcels at NSTI and is documented in the results and bibliographic reference databases (Appendices A and B, respectively).”

2011 Nuclear Radiation Maps of Treasure Island Housing made by the Navy


In 2011 the Navy conducted a radiological survey and found Radium, Thorium, Uranium, Radioactive Potassium and Radioactive Thallium under the housing at Treasure Island by driving a towed array of radiation detectors over the streets and yards producing a map of radiation for the Housing on Site 12 at Treasure Island Naval Base. This article will show many of the maps created of the Radiation at the housing on Treasure Island.

The materials were not cleaned up at the time, but these isotopes give off radiation at certain frequencies and by reading these frequencies we can know what types of materials are giving off the gamma and X rays of these specific isotopes. The Chart below shows the different frequencies and their corresponding isotopes listed across the top. This is gamma radiation. Alpha and Beta radiation require laboratory work to confirm their presence. So you would not be able to detect Plutonium in this study, which was used in the Radiation Training at Treasure Island.

The radiation was centered on the area of the island where the Navy conducted the Radiological, Chemical and Biological Training using mock ups of a ship, the USS Pandemonium, an airplane, and a field gun. Eventually the Navy would collect Radium objects that were in the first 10 inches of soil and place them in boxes to be sorted out later in 2018.

In response to the increase in radiation, the Navy extended the chain link fences in order to protect the residents from what turned out to be a nuclear disaster. See Survey Findings below.
