The head of each Federal department or agency that owns a Federal building shall conduct a study for the purpose of determining the extent of radon contamination in such buildings.

The study design shall include testing data from a representative sample of Federal buildings in each high-risk area identified in subsection (b). The study design also shall include additional testing data to the extent resources are available, including any reliable data supplied by Federal agencies, States, or other parties.
Not later than June 1, 1990, the head of each Federal department or agency conducting a study under subsection (a) shall complete the study and provide the study to the Administrator.
