The operator Tepco says the workers came in contact with the wastewater when a hose came off accidentally and have been taken to hospital as a precaution
Five workers were cleaning pipes at the system filtering wastewater for release into the sea when two were splashed after a hose came off accidentally, according to a spokesperson for operator Tepco.
Two others were contaminated when they were cleaning up the spill, the spokesperson added.
The radiation levels in the two hospitalised men were at or above 4 becquerels per square centimetre, the threshold which is considered safe.
