LANSDOWNE RADIATION SITE
Superfund Site Profile
The Lansdowne Radiation site is located in Lansdowne, Pennsylvania. From 1924 to 1944, a University of Pennsylvania chemistry and physics professor processed enriched radium ore in the basement of a home on Stratford Avenue. Processing activities resulted in radium contamination of the three-story house as well as two garages on the property, two garages on neighboring properties, about 243 feet of municipal sewer line, sidewalks, the street and soil on eight properties. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1991.
