Article: Continuous Leaking Of Radioactive Strontium, Cesium From Fukushima To The Ocean


“March 11 will be the 5th anniversary since the nuclear accident in Fukushima, Japan. The Tohoku earthquake and the series of tsunamis damaged the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) causing a massive release of radioactivity into the atmosphere and the Pacific Ocean. Since then, the Tokyo Electric Power Company (TEPCO) and the Japanese authorities have focused on controlling the water flowing in and out of the FDNPP and on decontaminating the highly radioactive water used as coolant for the damaged reactors (about 300 m3 a day, cubic meter = 1000 L). This cooling water is then stored in tanks and, to some extent, being decontaminated.

A new study recently published in Environmental Science and Technology, uses data on the concentrations of 90Sr and 134,137Cs in the coast off Japan from the moment of the accident until September 2013, and puts it into a longer-time perspective including published data and TEPCO’s monitoring data available until June 2015. This study continues the work initiated after the accident in 2011 by some of the authors. These and other partners from Belgium and Japan are currently involved in the European FRAME project lead by Dr. Pere Masqué that aims at studying the impact of recent releases from the Fukushima nuclear accident on the marine environment. FRAME is encompassed within the European COMET ”
