Japan’s Fukushima Disaster and Its Impact on Fish in the Pacific Northwest

If you have environmentalists as Facebook friends, you may have seen an image and headline making the rounds suggesting that leaking waters from the Fukushima nuclear reactor in Japan is poisoning the waters of the Pacific Ocean. As a passionate lover of wild Alaskan salmon, that had me worried. I’ve had moments of mild panic thinking that the bounty of the seas may be gone forever.

Salmon are the major fruit of harvest season for me. I was raised subsistence fishing in the waters of Southeast Alaska. I believe we are what we eat, and I am certain I am made mostly out of salmon! Spiritually, the salmon are a spiritual food. I understand the honor that Northwest Coast Native Americans give to the Salmon, honoring the sacrifice Salmon give to their Human allies, and I understand why the Celts call them ‘Salmon of Wisdom’ and ‘Salmon of Abundance.’

If the Pacific waters are contaminated, so are my blessed salmon. I decided to do a little research and find out what is going on.

In March 2011, a huge tsunami crashed into coastal Japan, devastating villages and damaging the Fukushima nuclear plant. TEPCO, the company responsible for the reactor, has been unable to effectively control the reactor. Cooling water, contaminated with radiation, has indeed leaked into the Pacific Ocean. Recently, TEPCO has admitted that the problem is worse than it previously let on.

This is horrible, awful news. What does this mean for those of us in western coastal states in the US? Not much, actually. Neither the State of Alaska nor the State of Washington are concerned for their fisheries. A skeptic might dismiss reports comng out of government agencies, but please remember that commercial fisheries are incredibly important to the economies of both states. Commercial fisheries in Alaska employ over 78,000 people and is a multi-billion dollar industry. Both states are monitoring air, water, and fish contamination levels daily and have found neglible results.

How can this be? Dilution. The Pacific Ocean is so large, so vast, that the radiation dumped into the ocean in Japan is diluted to safe or non-detectable levels. I think we also forget just how much pollution is dumped in our oceans and streams every day. Besides radiation and industrial and human wastes, plastic debris is the greatest threat to the health of our oceans. There is a hideous thing called the Great Pacific Garbage Patch, a massive collection (a ‘gyre’) of rubbish floating in the ocean. The gyre in the Pacific is just the largest of the gyres — each ocean has one!

For the most part, those of us that love wild seafoods from the Pacific Northwest don’t have to worry — at least, not about radiation from the Fukushima nuclear reactor. There are other threats to our fish: overfishing, fish farms, and closer-to-home sources of pollution in the waters.

Sadly, it is Japan that suffers the most from Fukushima’s meltdown. Their water, air and fisheries need serious cleaning up; their coastal communities still need rebuilding. As I give thanks to the Great Salmon for their life-giving abundance, I offer up prayers for the people and land of Japan.

    You are right, but you are also wrong.

    From the Washington Post, dated August 2013:

    “While many people assume that the ocean will dilute the Fukushima radiation, a previously-secret 1955 U.S. government report concluded that the ocean may not adequately dilute radiation from nuclear accidents, and there could be “pockets” and “streams” of highly-concentrated radiation.” *

    The article refers to a powerful current called the North Pacific Gyre, which sweeps past Fukushima. It is a fast-moving, circular current with the Hawaiian islands roughly in the middle. This current sweeps the West Coast all the way up to Alaska.

    At best we can conclude that some areas will be contaminated and others not. But what the media doesn’t do enough to explain is that not all forms of radiation are identical. Some forms are more likely to lodge in the thyroid, some in the bones, others in the gut or muscle tissues. When articles online suggest that Fukushima radiation levels have not risen far above background radiation levels they only muddle the matter. Comparing naturally-occurring background radiation levels to radioactive elements associated with the fission process could be compared to apples vs. oranges. All the while, other studies suggest no amount of radiation is safe, if only because they tend to accumulate over the course of our lives. In addition, there are individual considerations that ought to come into play vs. some blanket pronouncement of “safe” or “unsafe”. For instance, there are cancer survivors and radiology technicians who have reached their lifetime limit for exposure to radiation treatments. For them, over-exposure to sunshine is a risk let alone radiation-contaminated seafood.

    None of this is say that fish from the Pacific are entirely unsafe, only that we cannot presume that they are. The only responsible reaction in a case like this is stringent testing. To my knowledge, routine testing is not being done except on fish imports originating from Japan. Therein lies the problem: If we don’t seek, we don’t find. And yet, what we do not know can, indeed, hurt us.

    My personal take is this: For those in midlife, tuna and Pacific fish consumption in general probably isn’t worth worrying about. For pregnant women, children and college-age adults, however, there ought to be an advisory similar to that which exists for the purpose of limiting a pregnant woman’s exposure to tuna contaminated with mercury.

    According to the Washington Post blog, the salmon counts are way down, too:

    “[E]ach fish hitches a ride back to its home rivers and spawning grounds on the North Pacific current, the same one pulling the nuclear waste eastward.”
