No, a radiator does not contain freon, as freon is a refrigerant used in air conditioning systems, not in vehicle cooling systems. Radiators typically use coolant or antifreeze to regulate engine temperature. If there is a leak in a vehicle's cooling system, it would involve coolant rather than freon. However, if you are experiencing issues with your air conditioning system, it may indicate a freon leak in that specific system instead.

If it's still cooling, even inefficiently, it's definitely not the freon.
