The public's voice for Hanford cleanup, clean energy, and nuclear safety across the Northwest
Fortunately, as of August 2014 the Navy has removed this soil. However, the Navy has not disclosed how - or where - highly radioactive cesium and strontium were used and disposed of at Sand Point Naval Air Station. They likewise did not disclose the information about the Building 27 radium radiation to the public for three years.
In addition to the areas around Building 27, numerous other radioactive 'hot spots' have been uncovered, such as the grassy areas around Building 2 and the storm and sewer drain lines that run into Lake Washington at the hand launch beach and sailing dock.
The Navy has objected to the use of Washington State's toxic waste cleanup law (MTCA) standard and instead uses its own cleanup level based on a dose of radiation from exposure to contamination just two hours a day, twice a week. This cleanup standard is estimated to cause eight additional fatal cancers in every 10,000 adults exposed annually--and children are three to ten times more susceptible to cancer from the same dose.

Contaminated soil areas around Magnuson Park's Building 27
Magnuson Park is the second largest park in Seattle at 350 acres, located in the Sand Point neighborhood and on the former location of Naval Station Puget Sound. Due to this area's previous use as a military base, serious levels of radioactive contamination were identified in buildings and soils in 2010.
How serious? Areas of soil on the south and west sides of Building 27, which now houses Arena Sports (pictured below), had levels so high that if someone had sat on the soil year-round they would have received a radiation dose equivalent to 1,200 x-rays in one year.
