7 BILLION Bq/Kg Of Cesium & Over 7,500 Bq/Kg Of PLUTONIUM And AMERICIUM Detected 15 Km From Fukushima Plant

Flashback:

Scientists Detect Plutonium From Fukushima In Lithuania


Officials: ‘Hot’ materials with 7 billion Bq/kg of cesium found 15 km from Fukushima plant — “Most likely” came from Unit 3 — Over 7,500 Bq/kg of Plutonium and Americium (PHOTOS) (ENENews, Feb 14, 2014):

Follow-up to: Asahi: Highly radioactive ‘mystery objects’ found — Rumored to be pieces of Fukushima reactor buildings — 15 kilometers from nuclear plant (PHOTOS)

EXSKF, Feb. 13, 2014: […] four small pieces of debris found at the river mouth in Naraha-machi 15 kilometers from the plant may have come from Reactor 3. […] TEPCO disclosed the result of the analysis of the debris done by Japan Atomic Energy Agency […] TEPCO and JAEA’s conclusion [is that] small pieces of debris came from Fukushima I Nuclear Power Plant, most likely from the Reactor 3 building […] There will be no further analysis whether there is any contribution from MOX fuel […]

Selected radionuclides detected in Sample 3:

  • Plutonium-238, 239, 240 + Am-241 = 7,675 Bq/kg
  • Cesium-134, 137 = 7.3 billion Bq/kg
  • Cobalt-60 = 1,225,000 Bq/kg

Yomiuri Shimbun translated by EXSKF, Feb. 14, 2014: [The debris] could have been scattered by the hydrogen explosion in the reactor building, or they could have come from the ocean.
