BBC: TEPCO Sued by Eight US Soldiers Over Radiation Disclosure

The soldiers were part of the Operation Tomodachi, which was such a tremendous help to the people in the disaster-affected areas in Tohoku in the early days of the earthquake/tsunami disaster in March last year. Unfortunately, the disaster also involved the nuclear accident, but at that time hardly anything about radiation exposure for the US soldiers, or SDF soldiers, or Japanese and international volunteers, were even mentioned in the news.

Asahi Shinbun reports that these soldiers were on board USS Ronald Reagan.

See, people in Japan, this is how much you should also sue TEPCO for - demanding US$10 million each (860 million yen), plus punitive damage of US$30 million. Add one or two zeros on your claim form.

The problem of course is that that money, or any money being demanded out of TEPCO, will eventually come from Japanese taxpayers' pockets, now and in the future. TEPCO is owned by the national government.

USS Ronald Reagan was in the Korean Peninsula region when the March 11, 2011 disaster struck. The carrier was diverted to Japan, and was used as a floating base off the coast of Sendai, Miyagi. From Wiki entry:

The ship departed for an Asian deployment on 2 February 2011. On 11 March 2011, Reagan was in the Korean peninsula region for a long-planned exercise off Korea, but was redirected towards Japan to provide support after the massive 2011 Tōhoku earthquake and tsunami. The ship, stationed off Sendai, was used as a floating refueling station for Japanese military and coast guard helicopters flying relief missions in the area.[28] US Navy helicopters also flew relief missions from the carrier. On 14 March 2011, the ship was forced to relocate to avoid a radioactive plume from the Fukushima I nuclear accidents which had contaminated 17 crewmembers of three helicopter crews.[29][dead link] On 23 March, the Reagan's crew conducted a radiation decontamination operation to remove any further radiation hazards from the ship, which included scrubbing down any surface that could have been contaminated, including the flight deck and aircraft.[30]

The report on March 14, 2011 about the ship relocating is here. It says the 17 helicopter crews were exposed to one month worth of background radiation, and they were on a relief mission to Sendai, Miyagi.

Japan's Tepco sued by US sailors over radiation

Tokyo Electric Power Company (Tepco), owner of the crippled Fukushima Daiichi nuclear plant, has been sued by eight US sailors over radiation exposure.

They claim that Tepco lied about the threat posed by the leaks after the March 2011 earthquake and tsunami damaged the plant.

The soldiers were involved in relief operations after the natural disasters.

They have each sought $10m (£6m) in compensatory damages and $30m in punitive damages from Tepco.

The soldiers, who have filed the case in a US Federal Court in San Diego, also want Tepco to set up a $100m fund to pay for their medical expenses.

They have claimed that the utility provider created an impression that the level of radiation leaks from the nuclear plant did not pose any threat.

As a result, the sailors say they went to areas that were unsafe and were exposed to radiation.

When contacted by the BBC, Tepco acknowledged that it has been sued, but said that it had not received the actual complaint and so was not in a position to comment.

The lawsuit is the latest setback for Tepco which is already facing billions of dollars in compensation claims.

The radiation leaks resulted in thousands of people and businesses being evacuated from the areas surrounding the plant.

On Thursday, the firm said that it now expects the compensation costs to total at 3.24 trillion yen ($38bn; £23bn), up 697 billion yen from its earlier projection.

The firm has already received nearly 1tn yen in government aid.

The utility was, in effect, nationalised after the government took a 50.11% stake in the group in exchange for the capital injection.

In September this year, the US Department of Defense set up a special registry for the participants of the Operation Tomodachi.

US Department of Defense Sets Up "Operation Tomodachi" Radiation Exposure Registry

The whole-body radiation dose estimate for adults (older than 17) in Sendai, Miyagi during the 60 days from March 11 to May 11, 2011 may be as high as 1.2 millisievert, assuming being outside at all times with constant high physical activity levels.

Registry to Provide Japan Response Radiation Info

By Jim Garamone
American Forces Press Service

WASHINGTON, Sept. 5, 2012 – Though no Defense Department personnel or their families were exposed to radiation causing adverse health conditions following the nuclear accident in Japan last year, the department has established a registry to provide information to those who served in the stricken country.

The March 11, 2011, earthquake and subsequent tsunami off the coast of Japan caused extensive damage to the Fukushima nuclear power plant, and radiation leaked from the facility.

The Defense Department has established an Operation Tomodachi registry for the 70,000 U.S. service members, family members, DOD civilians and DOD contractors who were in Japan from March 12 to May 11, 2011, said Dr. Craig Postlewaite, DOD’s director for force readiness and health assurance.

“The concept of a registry evolved very soon after the crisis in Japan,” the doctor said in an interview with the Pentagon Channel and American Forces Press Service. “Initially, there was great emphasis placed on environmental monitoring, because we needed to monitor those levels to ensure that people weren’t adversely affected during the crisis.”

Commanders used the monitoring information to assess whether to evacuate personnel. The monitoring data, plus a policy that required the services to report daily precisely where every service member was, enabled the department to establish the registry, he said. “We then had the capability to provide information on estimated doses of radiation” for each person, Postlewaite said.

The Operation Tomodachi registry is being built in a secure database in which all personal information is protected. The dosage estimates cover 13 different shore-based locations, U.S. Navy ships located off the mainland of Japan and aircrews. It also incorporates about 4,000 U.S. responders who were issued radiation dosimeters. “The registry will be finished this calendar year,” Postlewaite said.

In addition to the registry, DOD is building a companion website to the registry. Individuals cannot be identified on the website, but people can click on a map to determine the exposures in a specific prefecture, base or area for those who spent most of their time on mainland Japan in the timeframe the registry covers. The website also has information on radiation doses from a medical standpoint.

The doses and other information in the registry and on the website have been peer-reviewed and agree with information provided by national and international groups – including the World health organization and the International Atomic Energy Agency, said Dr. Paul Blake, a senior health physicist at the Defense Threat Reduction Agency at Fort Belvoir, Va. Blake also serves as the Operation Tomodachi co-chair for the dose assessment and recording working group.

The radiation release from the nuclear plant came in two types, the doctor said. “One was the shorter-lived radioactive iodines,” Blake said. “If you inhale it or ingest it, it has the tendency to collect in your thyroid in your neck. We needed to look at the health risk associated with that.”

The other health risk is radioactive cesium. “Cesium can have a half-life of 30 years, so it is still over there in Japan,” he said.

So from a health risk viewpoint, DOD officials looked at a dose to the thyroid and a dose to the whole body, and “that’s how we prepared the dose assessment for our shore facilities,” he said.

“Both the thyroid and whole body doses are significantly lower than the occupational limits that the Nuclear Regulatory Commission provides for this country,” he added.

What people were doing was as important as where they were, Blake said. “The Marines, for instance, did a lot of humanitarian efforts. When you are out there pushing hard and sweating, you are drinking a lot more water, [and] you are breathing a lot harder,” he explained. “We needed to take into account radionuclides would enter the body at a faster rate than someone doing a more sedentary [job].”

Sex and age made a difference in the assessments also. Absorption of radionuclides changes depending on a person’s gender and age.

Officials also are concerned about children. “They can be more sensitive, because they are still growing,” Blake said. “Fortunately, our children were fairly far back from the actual source. The doses they received were safe.”

At the companion site "Operation Tomodachi Registry", users can view the dose estimate in locations where the US has military bases and where the US military did the disaster relief work after March 11, 2011. (In rem, of course...)

For example, if you were an adult (older than 17) in Yokosuka Base from March 11 to May 11, 2011,

(1 rem = 10 millisieverts)

Whole-Body Radiation Dose Estimate: 0.033 rem (or 0.33 millisieverts)
Thyroid Radiation Dose Estimate: 0.40 rem (or 4 millisieverts)

On the other hand, if you were a Marine clearing up the Sendai Airport and continued to carry out the mission in the nearby areas in Miyagi, you may have gotten

Whole-Body Radiation Dose Estimate: 0.12 rem (or 1.2 millisieverts)
Thyroid Radiation Dose Estimate: 1.20 rem (12 millisieverts)

These numbers are probably higher than the actual exposures, because:

"These estimates were calculated based on you spending 24 hours outdoors, having a constantly high physical activity level (and associated reathing rates), and being exposed to the radiation measured in the air, water and soil over the entire 60-day period." (from "Operation Tomodachi Registry Location-Based Radiation Dose Estimate Report")

Well, the US Marines may have done that. I remember watching them at the Sendai Airport on a TV news program, and how they hustled to get the airport open in no time. I didn't connect at that time that radioactive plumes from Fukushima I Nuclear Power Plant were passing over them. The cleanup operation (prep) started on March 16, 2011.

And yet, many cynical Japanese who want to consider themselves as "sophisticated" still say, "Oh they did it as a military training exercise, nothing to do with helping the Japanese."

While the Japanese government had the government buildings and public schools cleaned after the earthquake/tsunami, the US military was clearing the ports and roads so that people in the disaster affected areas could have access to outside help. If that was nothing but their military training exercise, that was much better than what the Japanese government was doing.
