Post Remedial Action Report, Lansdowne Radioactive Residence Complex, Dismantlement/Removal Project. Volume 4. Radiological Oversight and Certification
Abstract
During the period 1924-1944, a Univ. of Pennsylvania physics professor was engaged in the commercial production of radium sources for medical use. As a result of the radium enrichment activities, the entire residence, the surrounding land, and the adjoining residence became contaminated. In August 1985, this site was officially added to USEPA's list of hazardous sites targeted for cleanup (Superfund). Onsite radiological overview was provided to the U.S. Army Corps of Engineers for the remediation activities. The oversight included radiological surveying, laundry/waste water sampling, air sampling and logging of contamination in the soil. Additional oversight responsibility included verification that the soil remaining on the site, adjacent to the site and under the sewer line, as well as backfill soil were below the cleanup criterion of 5 pCi/g above the natural Ra-226 background level of 1.5 pCi/g. The exposure rate measurements from the restored site ranged from 8 to 11 micro-R/h, typical of background levels in this area. This report provides documentation that the cleanup criterion of 5 pCi/g of Ra-226 above background has been met.
