It sure is. Leaking radiator fluid only causes the coolant system to de-pressurize and not effectively cooling all the internal working engine parts. As to repair costs, one needs to evaluate the cost of repairs vs replacing the radiator. If the car is older, then replacing the radiator might be the way to go.
Take it to a radiator shop or purchase a new one. I agree, and will go even farther. I would replace the radiator unless there was considerable savings in repairing it. The repair is only as good as the person doing it.
Either the radiator hose is loose where it connects to the radiator or there is either a small hole in the radiator or in the radiator hose. Try checking the hose to see if it's loose or check for small holes in the hose or radiator.
a hole in the radiator
Yagnas are not at all useful for ozone repairing. They are just myths.
There may be a hole in the radiator?
Could be a small hole or even be corroded. Remember it is under pressure so a very small hole will squirt out. check all rad hoses also for tightness and condition. my radiator has plastic tanks and cracked after a lean mixture of coolant froze and expanded the plastic tanks.
Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.
you have a hole somewhere or replaces your radiator
If the hole is fairly small, yes, it can do that. First degrease and scrub the area, then warm the epoxy immediately before you put it on. If the 'hole' is a crack, drill a very small hole at each end of it (1/16 or 3/32 drill bit) this will stop the crack spreading. - This will NOT be a permanent repair - but now you have some time to find another radiator, possibly from a wreckers yard.

because it has a hole. or your radiator drain is loose
