We’ve heard good things and bad things about the method of extracting natural gas from shale that’s known as "fracking."
Fracking not only uses chemicals that can contaminate drinking and groundwater, it also releases large amounts of natural radioactivity from the ground into the air, ¬including Radium-226, which has a half-life of 1,600 years.

Several new studies report that the impact to the US West Coast from Fukushima may be larger than anticipated. Radiation from the March 11, 2011 power plant meltdown contaminated the entire northern hemisphere within days, especially the West Coast of the United States. US environmental monitoring agencies have so far declined comment on what, if any, impact this could have on the health of the population along the coast.
On the Bellona website, Charles Digges quotes a new scientific paper as stating that its research "clearly demonstrates how little dissipation [of radionuclides] occurred [between March 12 and 16] due to the nature of the rapid global air circulation system."

The operator of the Fukushima nuclear plant has been dumping almost a thousand tons per DAY of radioactive water into the Pacific ocean. Will the Pacific ocean dilute this enough so that it’s harmless once it reaches our shores? And what about the debris that it’s bringing along with it?

We know that Fukushima radiation is headed for the West Coast of the United States (as well as Alaska), but who would have guessed it would be carried along by bluefin tuna? These migrating fish traveled 6,000 miles across the Pacific Ocean to bring it here.
Five months after the Fukushima disaster, researcher Nicholas Fisher and his team decided to test Pacific bluefin tuna that were caught off the coast of San Diego. To their surprise, tissue samples from all 15 tuna captured contained levels of two radioactive substances–ceisum-134 and cesium-137–that were higher than in previous catches.
