Wall Street Journal, July 8, 2013: Fukushima Watch: Tritium Levels Soar on Coast at Fukushima Plant [...] More than two years after the devastating accident at Japan’s Fukushima Daiichi nuclear plant, operator [Tepco] is seeing levels soar of a radioactive element called tritium. The problem spot is on the coastal side of the plant’s heavily damaged No. 2 reactor, one of the areas where Tepco regularly monitors groundwater to check for radioactive elements that may have leeched from the plant’s partly melted fuel cores and into the environment. [...]
Jiji Press, July 8, 2013: Tokyo Electric Power Co. says 2,300 becquerels per liter of tritium was found in seawater sampled off its crippled Fukushima No. 1 nuclear power station Wednesday, the highest level recorded since the March 2011 accident. [...] It is feared that groundwater containing high levels of tritium may be leaking into the sea from the plant’s No. 2 reactor building.
