After the Fukushima Daiichi nuclear disaster happened back in 2011, Japan has been trying to keep its nuclear waste levels on a safe level. The spill was caused by a tsunami that was triggered by the Tōhoku earthquake, and considerable amounts of radioactive materials were dumped into the Pacific Ocean beginning on March 12. Reports have recently shown that the nuclear waste has “pockets” and “streams” of highly-concentrated radiation that is heading towards the Western Coast of the United States. However, by the time it reaches Hawaii, it will be so diluted that the Western Coast of the U.S. will be spared of any health threats.

“Earlier this month, a study published in Science China warned that radiation leaking from the Fukushima Daiichi nuclear power plant is becoming more concentrated as it crosses the Pacific Ocean, rather than dispersing, and that it is making a beeline for the west coast of the United States.” writes Sophie Cocke from the Huffington Post. “The study, coupled with recent disclosures by Tokyo Electric Power Company, or Tepco, that radiation-contaminated water continues to leak into the ocean, has rekindled public concerns about health dangers.”

Enough radioactive water to fill 132 Olympic-sized pools has flowed into the ocean, Bloomberg News reported recently.

Even though University of Hawaii scientists say that the Western Coast won’t be heavily affected by the runoff radiation, which has entered several thousands of miles of the Pacific Ocean, Japan now faces a large homeless population around the Fukushima plant. Not only is the ground unstable, but now the ocean space around Japan has also become unhealthy, harming its fishing industry greatly.
