Scientists have detected heightened levels of radioactivity in the waters along the west coast of Canada and the United States, which can be traced back to the Japanese earthquake nuclear disaster in Fukushima in 2011.
The radiation comes from Fukushima, Japan, where a nuclear disaster occurred at a power plant in March of 2011. A magnitude-9.0 earthquake and the resulting tsunami left the plant severely damaged, resulting in three core meltdowns. Researchers found heightened levels of cesium-134, a fairly short-lived radioactive isotope, in many of the water samples collected along the west coast since 2011. Cesium-134 has a half-life of about two years, meaning half of its material decays every two years. That's relatively quick when compared to the 30-year half-life of cesium-137, a byproduct of nuclear fission and weapons testing.
Four years after the 9.0 magnitude earthquake, the effects of the earthquake are still being tested. The continued efforts to collect and study the long term effects of earthquake damage on heavy infastructure may prove beneficial in construction considerations moving forward.
