Tokyo -

A former worker is seeking 11 million yen ($110 000) in compensation from the operator of Japan's Fukushima nuclear plant for exposing him to high levels of radiation after the 2011 tsunami.

The worker was part of a team sent to lay electric cables in one of the reactors 13 days after the disaster.

He said in a 2012 interview that the plant operator - Tokyo Electric Power Company - should have known about the high radiation levels and warned them.

He asked to be identified by only his first name, Shinichi, because of the social stigma of being labelled a troublemaker in Japan.

His exposure exceeded official limits, forcing him to stop working at the plant. It was not considered a serious health risk.

The lawsuit was filed on Wednesday in the Fukushima District Court. - Sapa-AP
