A water-purifying apparatus, for reducing the radon content of radon-contaminated water, includes a reactor tank for treating the radon-contaminated water, a radon-releasing structure arranged in the upper part of the reactor tank to receive water from a first pump adapted to supply water from a source of water containing radon-contaminated water, the water from the radon-releasing structure accumulating in the reactor tank, an inlet duct extending between the first pump and the radon-releasing structure, an outlet duct from the reactor tank, the outlet duct being connected to a water consumption system, and a radon-gas outlet from the reactor tank. In a mixing structure, water from the first pump is mixed with water from the reactor tank with the aid of a second pump in order to produce such a water flow in the radon-releasing structure as results in effective radon release. The radon-releasing structure is in air communication with the surroundings of the reactor tank, so that air, via this air communication, is entrained with the water, which is supplied to the radon-releasing structure via the mixing structure, with a view to admixing air with the water and, hence, releasing the radon.
