World: Radioactive water leaks from Fukushima nuclear site
- 45 metric tons of radioactive water got loose from Fukushima source
- » How bad was it? The water leak was found Sunday on a device used to purify the seawater used to cool off damaged reactors. They stopped the leak by stacking sandbags against the concrete barrier surrounding the device. The water itself, authorities say, contained higher-than-usual levels of cesium 137, a radioactive substance. It’s not clear that any of this water made it to the Pacific Ocean. The reactor was greatly damaged during the March earthquake.
