The US West Coast is likely to get a hit from very low levels of radiation - leaked from the Fukushima nuclear reactor - next month. Scientists have reported that the radiations are not strong enough to pose any threat to humans and animals.

Ken Buesseler, a chemical oceanographer at the Woods Hole Oceanographic Institution, presented a study on the issue last week during a conference of the American Geophysical Union's Ocean Sciences Section. He claimed that current models predict that contaminated water had been leaking from the Fukushima reactor, which is now making its way to ocean waters along the US Coast.

Tokyo Electric Power Company, which operates the plant, also agreed with the report for the first time to admit that the reactor was leaking.

Buesseler said, "I'm not trying to be alarmist. We can make predictions, we can do models. But unless you have results, how will we know it's safe?"

It has been three years now when Japan tsunami caused meltdown in the reactor. It all started on March 11, 2011, when the coast of Japan was hit by a 9.0 magnitude earthquake, which triggered a tsunami with waves as high as 133 feet. During the catastrophe event, more than 15,000 people died and 6,000 suffered injuries.

The earthquake and tsunami cut the power supply in the cooling pumps at the Fukushima Daiichi nuclear power plant complex. As a result, meltdowns were caused at three reactors.

It was reported last week that some Cesium 134 has already made it through Canada, in the Gulf of Alaska area. The models have suggested that north of Seattle would be the first to receive get polluted and then the coast.

But, by the time radiations will reach there, the material will be so diluted that it would not be harmful by any means. Decaying is also seen in radiations. For example, life of Cesium 134 is four years, which means that its intensity will be less than half of its original after that period.
