Pangea contracted with Washington University in St. Louis
to provide radiological decontamination of a Physics Department laboratory
previously contaminated by experimental operations associated with the
Manhattan Project.
The laboratory was surveyed and determined to be
contaminated with enriched uranium and associated daughter products on
approximately 650 square feet of floor, wall, and ceiling surfaces.
Asbestos abatement procedures were performed prior to the radiological
work. Pangea personnel
performed all of the radiological decontamination of this project.
Concrete surfaces were decontaminated using pneumatic floor scabblers in
conjunction with rotary scalers and needle guns. Clay block wall portions
that could not be decontaminated were removed and packaged in drums for
disposal in accordance with applicable NRC and DOT regulatory criteria.
The total volume of radioactive material from this project was
approximately 84 cubic feet.
The project scope included:
-
Records/archives
review
-
Radiological
characterization
-
Development
of work plans and Radiation Work Permits, and provision of health
physics/radiation protection monitoring to support the remediation
-
Site
