LOS ANGELES-October 28, 2011 --
Federal authorities raided Los Angeles-area pharmacies Thursday, arresting 16 people in an alleged $18 million scheme to defraud Medicare that included the recruitment of veterans, homeless people, the poor and elderly. Tokyo's Setagaya city council had detected radioactivity exceeding that of an evacuation area about 25 miles (40 kilometers) from the Fukushima Dai-ichi plant at a roadside spot after concerned parents monitoring for radiation sought further tests.
It said Thursday the cause is most likely the unspecified content of several old bottles, not the tsunami-hit nuclear plant. It says radioactivity from the bottles exceeded the measurable limit on a low-dose counter.
Police are investigating the possible illegal possession of radioactive materials.
Officials say exposures at the spot wouldn't pose a health danger.
