Typically means you've got a blown head gasket.
The head gasket seals off the combustion chambers as well as the oil and water as it circulates between the head and the block. Sounds like the head gasket has gone bad between the oil and radiator fluid and the two fluids are mixing.
I'd get it checked to verify that it is indeed oil in the radiator fluid, or just very dirty radiator fluid.
