WASHINGTON — American Navy officials in Japan said early Monday that 17 military personnel who had been aboard three helicopters assisting in the earthquake relief effort had been exposed to low levels of contamination.
Cmdr. Jeff A. Davis, a spokesman for the American Seventh Fleet in Japan, said the Navy personnel — who apparently had flown through a radioactive plume from a damaged nuclear power plant — had been ordered to dispose of their uniforms and to undergo a decontamination scrub that had successfully removed radioactive particles.
“They received very, very low levels of contamination,” Commander Davis said in a telephone interview from Japan early Monday.
“It certainly is not cause for alarm,” he said. “It is something we have to watch very carefully and make sure we are able to monitor, and to mitigate against this environmental hazard.”
