16 US ships that aided in Operation Tomodachi still contaminated with radiation, By MATTHEW M. BURKE | STARS AND STRIPES March 13, 2016 CAMP FOSTER, Okinawa — Sixteen U.S. ships that participated in relief efforts after Japan’s nuclear disaster five years ago remain contaminated with low levels of radiation from the crippled Fukushima Dai-ichi nuclear power plant, top Navy officials told Stars and Stripes.
In all, 25 ships took part in Operation Tomadachi, the name given for the U.S. humanitarian aid operations after the magnitude-9.0 earthquake and subsequent tsunami on March 11, 2011. The tsunami, whose waves reached runup heights of 130 feet, crippled the Fukushima plant, causing a nuclear meltdown.
In the years since the crisis, the ships have undergone cleanup efforts, the Navy said, and 13 Navy and three Military Sealift Command vessels still have some signs of contamination, mostly to ventilation systems, main engines and generators……
The Navy has acknowledged that the Reagan passed through a plume of radiation. Navy images showed sailors with their faces covered, scrubbing the deck of the Reagan with soap and water as a precautionary measure afterward. The Reagan and sailors stayed off the coast of Japan for several weeks to aid their Japanese allies.
The multibillion-dollar ship, projected to last at least 50 years after its launch in 2001, then was taken offline for more than a year for “deep maintenance and modernization” at the Puget Sound Naval Shipyard and Intermediate Maintenance Facility in Bremerton, Wash., according to Navy officials…….
Sailors who performed the work said it entailed entering spaces deep within the ship, testing for high levels of radiation, and if it was found, sanding, priming and painting the areas. They say there were given little to no protective gear, a claim that the Navy denies……
Eight Reagan sailors, claiming a host of medical conditions they say are related to radiation exposure, filed suit in 2012 against the nuclear plant’s operator, the Tokyo Electric Power Co. The suit asserts that TEPCO lied, coaxing the Navy closer to the plant even though it knew the situation was dire. General Electric, EBASCO, Toshiba Corp. and Hitachi were later added as defendants for allegations of faulty parts for the reactors.
A spokesman for TEPCO declined to comment for this story because of the sailors’ lawsuit, which was slated to go forward pending appeals in the U.S. 9th Circuit Court of Appeals.
The illnesses listed in the lawsuit include genetic immune system diseases, headaches, difficulty concentrating, thyroid problems, bloody noses, rectal and gynecological bleeding, weakness in sides of the body accompanied by the shrinking of muscle mass, memory loss, leukemia, testicular cancer, problems with vision, high-pitch ringing in the ears and anxiety.
The list of sailors who have joined the lawsuit, which is making its way through the courts, has grown to 370…….
Shinzo Kimura — a professor at Dokkyo Medical University in Japan who has studied radiation exposure from Hiroshima and Nagasaki to Chernobyl and, now, Fukushima — said it wasn’t too early for sailors to show symptoms of exposure-related conditions. Doctors have seen conditions in children living near the plant that surfaced earlier than would normally be expected.
Kimura, hired by the Nihonmatsu city government for his expertise in the field, was the first scientist on the ground taking readings in the wake of the Fukushima disaster. He said each person and the way their body is affected by radiation is different.
While unable to definitively say if the sailors were sickened by the radiation, Kimura reasoned that the levels aboard the Reagan were high enough to cause illnesses. Otherwise, he said, why go through the bother of repeated cleanings to lower radiation levels?
“It is impossible to speculate or calculate how much the doses were before the two decontamination works,” he said. “The U.S. military is very good at risk-management. Considering that, it is assumed that decontaminations were conducted twice because the levels were not favorable.”
