Stop Fukushima Radioactive Ocean Dump

The Pacific science community, including the Pacific Islands Forum, their expert scientific panel, the National Association of Marine Labs (an organization of over 100 labs including Monterey Bay Aquarium Research Institute, Stanford, and The National Oceanic and Atmospheric Administration), and more, are uniting to say: STOP THE DUMP. The health of the ocean, and ultimately humans is at stake. Shark Stewards has joined an Ocean Health Alliance and Save the Pacific Ocean to advocate against Japan’s proposed illegal discharge of irradiated water into the North Pacific Ocean.


  • 1.3 million tons of radioactive waste water from the Fukushima nuclear meltdown will be released into the Pacific ocean sometime in the Spring or Summer of 2023.

Why is this happening?

  • TEPCO, the Tokyo Electric Power Company, cites storage issues, yet there is a 12-mile radius of land within the exclusion zone where additional tanks could be built.

Why do we care?

  • There are 64 radioactive nuclides in this water, including strontium-90 (Sr-90), cesium-134 (Cs-134), cesium-137 (Cs-137), iodine-129 (I-129), ruthenium-106 (Ru-106), antimony-125 (Sb-125), and cobalt 60 (Co-60), carbon-14 (C-14) and tritium (T).
  • TEPCO created a processing system, called Advanced Liquid Processing System (ALPS), but they haven’t proven it works to remove all of these nuclides. The data they’ve provided is messy and biased, and only measures 19 out of 64 nuclides. Their data does not follow sound scientific principles.
  • TEPCO has a reputation for lying about and covering up nuclear waste. 
  • Tritium is a big nuclide in question because the ALPS processing system can’t treat tritium and will release it into the ocean.
  • Tritium, including organically bound tritium (OBT) found at many other reactor sites, is bad to ingest. Tritium bioaccumulates, meaning it works its way up the food chain. When ingested, it causes DNA mutations, which is very serious, causing cancers and organ failure, with detrimental effects on fetal development.
  • Remember when they told us Mercury in tuna is bad? That’s because of bioaccumulation, too. It’s like that, but concentrating radioactive materials into your food, which mutate your DNA— causing cancers and organ failure, with detrimental effects on fetal development.
  • We cannot take this back. Once the waste is in the ocean, it stays there. Some of the nuclides in question, if released, would remain in the ocean for multi-millions of years.  
  • Common misconceptions are that this waste can be diluted and will be safe. However, The assumption that “dilution is the solution to pollution” is scientifically outdated and ecologically inappropriate. That is even more so in the case of the proposed discharges, which will inflict substantial damage to fisheries in Japan, and beyond.
  • Tritium requires 100 years to break down completely. It should be stored until it breaks down.
  • “There is no safe level of exposure and there is no dose of radiation so low that the risk of a malignancy is zero”–Dr. Karl Z. Morgan, dubbed the father of Health Physics.
  • “…there is no safe level of exposure to ionising radiation, and the search for quantifying such a safe level is in vain.”—Rosalie Bertell, PhD.
  • There are alternatives. Instead, they could remediate the radioactive material FAR MORE AFFORDABLY by storing it safely in cement, or using bioremediation techniques like oysters which concentrate the radioactive material into their shells.


  • We urge TEPCO, the Japanese government, the NRA, and the IAEA to STOP THE DUMP. They have not proven their methods work. They have not operated with scientific due diligence. The health of the world is at stake.
  • We also ask the IAEA and NRA to update their nuclear dump standards to be in line with the latest science.

News Coverage: 

  • Incomplete scientific coverage: Important global media companies like the NYT have written about this, but unfortunately did not dive into the science about how dangerous this is. They seem to have regurgitated TEPCO’s talking points. The NYT article quotes outdated science that says Tritium is relatively safe, however latest science shows that ingesting tritium mutates mitochondrial DNA, causing cancers and organ failure, with detrimental effects on fetal development. The safety standards are out of date with the science.
  • Well-researched coverage: Japan Times, for instance, actually dove into the science from the expert scientist panel.  The Guardian’s opinion piece shares more scientific details and concerns of the PIF.

“Tuna caught off California carry radiation from the Japanese disaster, Stanford scientist finds”

“Cesium-137 can get into your body if it’s inhaled or ingested. Exposure to radiation from cesium137 can result in malignant tumors and shortening of life. “

“Scientists say impact of long term low-dose [radiation] exposure to the environment and humans are unknown, and that tritium can have a bigger impact on humans when consumed in fish than in water.”
