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

Woods Hole Oceanographic Institution’s Center For Marine And Environmental Radiation:

  • Location: 32°57’0.00″N; 117°17’60.00″W [1.8  miles off the coast of Del Mar, California]
  • Sample Date: Apr 04, 2015 11:36
  • Depth: 3m
  • Cs134: 1.5 ± 0.1Bq/m3
  • Cs137: 6.9 ± 0.2Bq/m3

**********************************

The sample was taken just over a mile off the coast of Del Mar, CA – located about 15 miles north of San Diego and 100 miles south of Los Angeles. The only other location Woods Hole has reported detecting nuclear waste from Fukushima Daiichi along the shoreline of North America is in Ucluelet, Canada about 1,200 miles to the north of Del Mar.

7.2 becquerels per cubic meter of Cesium-134 and Cesium-137 was measured in a Ucluelet sample taken in February 2015. The Del Mar sample had 8.4 Bq/m3.

Results for other Fukushima Daiichi-derived radionuclides were not posted. According to media reports, “The plume also contains other radioactive material, including Strontium 90… radioactive isotopes of iodine, low levels of plutonium and tritium might be in the plume.”

According to Woods Hole scientist Ken Buesseler, “As the plume begins to arrive along the West Coast [it] will actually increase in concentration… no public agency in the US is monitoring the activities in the Pacific… Without careful, extensive, consistent monitoring, we’ll have no way of knowing how much radiation from Fukushima is reaching our shores, and how it could affect life in the ocean.”
