To provide for essentially uniform ultraviolet (UV) irradiation of all the nails of all the fingers of a hand of a user, a radiation source of essentially horseshoe shape is placed within a housing. The plane, in which the radiation source is located, is inclined with respect to the bottom wall (2) of the housing, on which the hand of the user is supported. The radiation is directed to impinge on the nails at about 90°. The nail of the thumb also has radiation impinging at about 90°. The radiation source may be a single, bowed, UV-emitting lamp, or may be built-up of straight lamp sections (12,13), e.g., two lamps along the housing sides for irradiating the thumbs, and one or two lamps across the housing to irradiate the nails of the index finger through little finger.
