Japan to Assess Its Dumping of Toxic Water, Wall Street Journal, April 14, 2011:

… A new concern arose late Wednesday with the discovery that the radioactivity of water in reactor No. 4′s spent fuel pool was vastly higher than normal. A sample of water taken Tuesday contained 220 becquerels of iodine-131 per cubic centimeter. That compares with a level of just 0.01 becquerels or less for normal spent fuel pools. Such pools hold previously used nuclear fuel, allowing it to slowly cool down over a matter of years. …
