Radioactive waste up to 22 times the expected level was found in a kindergarten play area at an elementary school in Florissant, according to a recently released report.
Boston Chemical Data Corp. examined soil, dust and plants at Jana Elementary School in the Hazelwood School District.
The school, off Patterson Road, sits in the flood plain of Coldwater Creek, which was contaminated by waste from nuclear bombs manufactured during World War II.
Samples taken on Aug. 15 from Jana’s library, kitchen, HVAC system, classrooms, fields and playgrounds found “far in excess of the natural background” of radioactive isotope lead-210, polonium, radium and other toxins
