"Radioactive Strontium From Fukushima Disaster Found in 10 Prefectures"

"Radioactive strontium-90 from the crippled Fukushima No. 1 nuclear power plant has been detected for the first time in 10 prefectures outside Miyagi and Fukushima, the science ministry said July 24."

"The highest reading was in Ibaraki Prefecture and nearly matched the maximum level of strontium-90 recorded in Japan following the Chernobyl nuclear disaster. The nine other prefectures are Iwate, Akita, Yamagata, Tochigi, Gunma, Saitama, Chiba, Tokyo and Kanagawa.

But experts say the current levels of strontium-90 will have little impact on health."
