Children enrolled in the Library of Congress's (LoC) Little Scholars child-development center may have been exposed to an unsafe level of a carcinogenic gas, and their parents have yet to be notified.
While completing new LoC requirements for its reaccredidation process in January, the daycare center requested a radon test from the Public Health Service, Architect of the Capitol (AoC) spokeswoman Cynthia Snyder said.
"There were 33 tests taken and one of the readings was about 4.0," Snyder said. The Environmental Protection Agency (EPA) recommends that any test registering radon levels of more than 4 picocuries per liter (pCi/L) be repeated, according to Snyder. Last month, the Public Health Service retested the area and found the radon level to be 2.1 pCi/L.
