The 4,727-page EPA report “Draft Final Radiological Characterization of Soils, Area IV and the Northern Buffer Zone, Area IV Radiological Study” showed that the radiation contamination across Area IV of SSFL was far greater than previously known. Huge hits of strontium-90, plutonium 239-240 and cesium-137 are mapped showing wide swaths of radioactive soil, roads, and reactor remains. One Area IV road is contaminated with strontium-90 at 67 times background. Cesium-137 clocks in at 1,016 times normal in one spot and a stupefying 1,918 times background in another. Nearby, a borehole under an old reactor finds a hot spot deep beneath the surface: Plutonium 239-240 over 24 feet down intensely ionizing at over 92 times background. What makes these enormous radiation readings even more alarming is the fact that most of Area IV has supposedly been remediated, twice in some cases. Plus, government surveys signed off on these areas declaring them fit for unrestricted use.
