The study, "Too Close to Home:Nuclear Power and the Threat to Drinking Water", says that 652,000 people in Illinois are living within 50miles of an active nuclear power plant, the distance the Nuclear Regulatory Commission uses to measure risk to food and water supplies.

As the nuclear facilities get older, leaks are more common. In fact, 75% of U.S. nuclear plants have leaked tritium, a radioactive form of hydrogen that can cause cancer and genetic defects.

In December 2005, investigators discovered tritium in a drinking water well near Braidwood Nuclear Generating Station in Illinois. Much higher levels than the standard were found on the plant grounds.  

Director of the Chicago-based Nuclear Energy Information Service, Mr.David Kraft said that Tritium should be considered a major problem issue with nuclear plants, especially among the Great Lakes region's 33 nuclear reactors which sent more tritium than the other U.S. reactors.

The study recommends the United States should move to a future without nuclear power plants, and expanding the production of clean and renewable energy like wind and solar power.

In Korea, there are 21 nuclear power plants in action and 7 in construction. After the Fukushima tragedy, our government went through the inspection of all running plants, and announced they were safe.

Not only government, but non-profit organizations or watch-dogs should do follow up researches and inspection to keep people safe.
