WASHINGTON (AP) — More U.S. military crews were exposed to radiation Tuesday as the Pentagon ramped up relief flights over a Japan reeling from an earthquake, tsunami and nuclear crisis.
The Defense Department said the Navy started giving anti-radiation pills to some of those exposed, and Americans on two military bases south of Tokyo were advised to stay indoors as much as possible. Meanwhile, U.S. aviation and energy officials also worked with Japanese counterparts on the nuclear developments.
With more aid for victims on the way, the U.S. Navy said it was redirecting three ships to work in the Sea of Japan on the country’s west coast rather than risk the hazards of radiation and the debris field in the waters off the east coast.
Sensitive air monitoring equipment on the aircraft carrier USS George Washington detected low levels of radioactivity from the Fukushima Dai-ichi nuclear power plant as the carrier sat pier-side at Yokosuka, Cmdr. Jeff Davis, a spokesman for the U.S. 7th Fleet, said Tuesday.
Davis said that while there was no danger to the public from the radiation levels, the commander recommended as a precaution that military personnel and their families at the two bases, Yokosuka and Naval Air Facility Atsugi, limit their outdoor activities and seal ventilation systems at their homes as much as possible.
At the White House Tuesday, spokesman Jay Carney said that unlike some other countries the U.S. was not recommending that American citizens leave Tokyo over radiation concerns. Tokyo is about 170 miles from the nuclear plant and slightly elevated radiation levels were reported in the capital, but Japanese officials said the increase was too small to threaten the 39 million people in and around the city.
Nonetheless, Austria said it is moving its embassy from Tokyo to Osaka and France recommended that its citizens leave the Japanese capital.
Carney said that U.S. officials have determined American citizens in Japan should follow the same guidance Japan is giving to its own citizens. The Japanese government has warned people within 20 miles of the nuclear reactor complex damaged in the earthquake and tsunami to stay indoors to avoid exposure, but officials have said radiation levels in Tokyo didn’t represent a threat.
The U.S. embassy in Tokyo has told Americans to avoid traveling to Japan.
The Navy said Monday that radiation was detected by another carrier, the USS Ronald Reagan, and that 17 helicopter crew members had to be decontaminated after returning to the Reagan from search and rescue duty. The Navy said more crews were exposed to very low levels of radiation Tuesday and had to be decontaminated.
Potassium iodide pills were given to a small number of those crew members as a precaution, said Col. Dave Lapan, a Defense Department spokesman.
The Reagan strike group — which includes seven other ships — flew 29 missions Tuesday to deliver 17 tons of food, water, blankets and other relief supplies ashore.
“We continue to monitor the winds closely, moving our ships and aircraft as necessary to avoid the wind line from the Fukushima power plant,” Davis said. “Our aircraft and aircrews returning from missions ashore are being monitored carefully for contamination, and we are conducting decontamination procedures as necessary when it is detected.”
A three-ship amphibious group, including the 31st Marine Expeditionary Unit aboard the USS Essex, was directed to position itself in the Sea of Japan and was to arrive Thursday for other relief duties.
Meanwhile, Energy Secretary Steven Chu said his department has assembled a team of 34 people and sent 7,200 pounds of equipment to Japan to help monitor and assess the situation with the nuclear reactors.
Carney said Tuesday that President Barack Obama has asked U.S. nuclear regulators to incorporate information and lessons learned from the Japan incident into its overall reviews of the safety and security of reactors in the U.S.
