TOKYO, April 30 (Xinhua) — About 800 tera becquerel of Cesium- 137 is going to reach West Coast of North America by 2016, equivalent to 5 percent of the total Cs-137 amount discharged to the pacific ocean after the Fukushima nuclear disaster, a Japan researcher was quoted by Kyodo recently.<\/p>\n
<\/p>\n
<\/p>\n
Michio Aoyama, a professor from Japan’s Fukushima University Institute of Environmental Radioactivity said about 3,500 tera bq of Cs-137 have been released to the sea and 1.2 to 1.5 tera bq of Cs-137 released to the air, then fell to the sea from the crippled nuclear plant.<\/p>\n
<\/p>\n
<\/p>\n
Part of the radioactive substances have been observed to move eastward at a speed of 7 kilometers and 3 kilometers one day before March and August 2012 respectively, Aoyama said.<\/p>\n
<\/p>\n
<\/p>\n
However, Cs-137 levels detected at U.S. beaches were 1 to 2 bq per cubic meter, much lower than the safety limit for cesium levels in drinking water by the World Health Organization.<\/p>\n
<\/p>\n
<\/p>\n
“Even if all the 800 tera bq Cs-137 have arrived, the radiation levels will stay at relatively low level that aren’t expected to harm human health,” said Aoyama.<\/p>\n
<\/p>\n
<\/p>\n
The Woods Hole Oceanographic Institution of America has announced early April that they detected Cs-134 for the first time in a seawater sample from the shoreline of North America. Cs-134, with a half-life of only two years, is an unequivocal marker of Fukushima ocean contamination, said researchers.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
