FRESNO, Calif. --An aircraft carrier with Central Valley sailors on board is dealing with a contamination scare. The U.S.S. Ronald Reagan is off of Japan's coast with 5,000 sailors onboard. Monday, the U.S. Navy announced 17 crewmembers had been exposed to radiation. Though 600 sailors onboard are based at N.A.S. Lemoore, officials don't believe any of those affected are Lemoore based.
