Corrosion – this is the most common cause of sludge build-up in a radiator. Radiators, like most parts in your engine, are made of metal. Over time, antifreeze can degrade. As it degrades, coolant loses its protective qualities, PH levels change, and corrosion sets in.

Why is there oil in my coolant but no coolant in my oil?

The reason no coolant is in the oil is because it is a high pressure leak, oil pressure is always higher than coolant pressure when running, so if the leak only happens at 20-25psi or above, coolant will never get into the oil. Other than that it could be a head gasket as suggested but is rare.
