Tokyo Electric Power (Tepco) said initial reports of levels 10m times higher than normal in parts of the No 2 reactor were inaccurate, although it was unable to say by how much.
The initial report said the worker who made the measurement, carried out on a pool of water in the reactor's basement turbine building, had fled before taking a second reading.
The worker's discovery prompted another evacuation at the site, halting work to pump and store radioactive water that has built up in the turbine buildings of three of the plant's six reactors.
