Could nuclear cloud cross Pacific Ocean?

Radioactivity may reach US, but not enough to cause major health problems

GENEVA / LOS ANGELES - Winds are dispersing radioactive material from Japan's quake-hit Fukushima Daiichi nuclear power plant over the Pacific Ocean, away from Japan and other Asian countries, the World Meteorological Organization (WMO) said on Tuesday.

But the United Nations agency warned that although winds had blown particles offshore so far, weather conditions could change and it was closely monitoring satellite and other data.
