The lawsuit was filed in U.S. District Court in San Diego last week against Tokyo Electric Power Co., which is owned by the Japanese government. Plaintiffs include the infant daughters of two of the sailors.
The 37-page suit charges that the utility lied about the level of radiation in the atmosphere following the March 2011 disaster. The sailors served on the San Diego-based aircraft carrier USS Ronald Reagan. They claim they were exposed to harmful levels of radiation that could result in cancer and a shorter lifespan.
An email seeking response from the utility's corporate office was not immediately returned.
