Cesium 134 and cesium 137: The two isotopes that were released into the Pacific Ocean when an earthquake ruined the Fukushima Daiichi nuclear power plant on the eastern coast of Japan in 2011. The panic over the leakage was instantaneous in the US—but a new study shows how long it really took.
The Tōhoku earthquake and tsunami may have struck three years ago, but radioactive water from Japan's beleaguered Fukushima nuclear power plant is now being detected near Canada's West Coast. Scientists will be monitoring North American shores for the next two months, but projections point to good news.
The operator of Japan's infamously crippled Fukushima nuclear power plant recently attempted to move some radioactive water from one tank to another. In the process, it spilled four tons of deadly sludge.
