Woods Hole Oceanographic Institution: In the aftermath of the 2011 tsunami off Japan, the Fukushima Dai-ichi Nuclear Power Plant released cesium-134 and other radioactive elements into the ocean at unprecedented levels. Since then, the radioactive plume has traveled west across the Pacific… any cesium-134 detected in the ocean today must have come from Fukushima… We expect samples from the surface waters of the western Pacific that have not been contaminated by the Fukushima source to have 137Cs activity of between 1 and 2 Bq/m3 and for 134Cs to be “below detection.”

California Coast, Aug 17, 2015:

  • Cesium-134 @ 0.3 Bq/m3 (becquerels per cubic meter)
  • Cesium-137 @ 4.4 Bq/m3
  • Total Cesium @ 4.7 Bq/m3

Oregon Coast, Aug 19, 2015:

  • Cesium-134 @ 0.5 Bq/m3
  • Cesium-137 @ 2.9 Bq/m3
  • Total Cesium @ 3.4 Bq/m3

Washington Coast, Jun 27, 2015:

  • Cesium-134 @ 0.5 Bq/m3
  • Cesium-137 @ 3.4 Bq/m3
  • Total Cesium @ 3.9 Bq/m3

Alaska Coast (near Canada), Jun 23, 2015:

  • Cesium-134 @ 0.24 Bq/m3
  • Cesium-137 @ 1.9 Bq/m3
  • Total Cesium @ 2.14 Bq/m3

From August: Fukushima nuclear waste detected along Southern California coast — Highest levels seen anywhere in North America since testing program began — 8.4 Bq/m3 of radioactive cesium measured near beach between Los Angeles and San Diego (VIDEO & MAP)

From April: “Scientists detect Fukushima radiation on North American shores” — Coastal communities ‘concerned’ — Over 7 Bq/m3 of cesium from dock in Pacific Northwest — Professor: It indicates arrival of other radioactive substances — “Represents potential radiological health risk” (VIDEO)
