No it is not. It could be a problem with the radiator, a radiator hose or a water pump. In any situation, it could cause the motor to overheat and damage it severely.
heater hose?
The radiator will need to be replaced. Sometimes, it may seem that the radiator itself is leaking but it could be the radiator "hose" that is leaking. In this case, the radiator hose needs to be replaced and clamped tightly.
Having to add collant & coolant leaking from the hose.
tighten up the hose you think it is and see if it still leaks if it does still leak then its either a cracked hose or crack in your radiator
