ily elemental and can cause brain damage. Inorganic mercury,
found in soil, water, and food, can damage the kidneys. Organic
mercury, in a form called "methylmercury," is found in fish and
shellfish and can cause birth defects and brain damage.
/ PCB Releases from Oak Ridge Facilities - PCBs were used as a
fire-retardant in transformer oils throughout the ORR until the
mid-1970s. In the mid-1970s the United States banned the use of
PCBs because of evidence that they are harmful to human health,
potentially causing cancer and hormone-like effects.
/ Radionuclide Releases from White Oak Creek - White Oak Creek
flows through ORNL and into White Oak Lake, ultimately dis-
charging into the Clinch River. Radioactive contamination has
entered the creek from numerous sources, including shallow land
burial sites in Melton Valley and waste ponds in Bethel Valley.
This study concentrated on the potential health impact from eight
radionuclides: cesium-137, strontium-90, cobalt-60, ruthenium-
106, niobium-95, zirconium-95, iodine-131, and cerium-144.
Project investigators have also screened a wide variety of other materials,
including uranium releases from Y-12 and K-25. The uranium study, although

analysis of data quality and an evaluation of potential
health effects. Emissions from Y-12 are of particular
concern because the Scarboro and Woodland communi-

processes, releases and potential health effects.
Classified material was examined by contractors and
state officials with clearances, and much of this information relevant to the stud-
