Radioactive Waste Found Outside West Lake Landfill in Missouri

摘要

Newly uncovered documents show radioactive waste may have contaminated areas outside the West Lake Landfill in Bridgeton, MO. Soil samples taken in 2005 by the Missouri Department of Natural resources found at least three places along St. Charles Rock Road with unusually high levels of Thorium 230, a radioactive isotope that has been linked to certain types of cancer. Thorium 230 does occur naturally. A spokesman for the St. Louis Army Corps of Engineers tells NewsChannel 5 the isotope is usually found in north St. Louis County in average levels of 1.5 pCi/g. Three soil samples collected by the DNR found areas with 8.81 pCi/g, 5.41 pCi/g and 4.41 pCi/g respectively.
