Radiation safety: What you should know

You might be a little freaked out about 11,500 tons of radioactive water being dumped into the Pacific Ocean in Japan, where workers are still scrambling to stabilize an earthquake-crippled nuclear power plant called Fukushima Daiichi. In fact, the words "radiation" and "nuclear" give many people the creeps.

And that's partly because these are concepts that you aren't too familiar with; take a minute to learn the basics here. When you get down to the actual risks involved in the Japan nuclear disaster, things aren't so bad for the general public.

It's true that radioactive particles from a nuclear disaster like this do get into the food supply, but so far there's no indication that there's cause for alarm. The particles emitted from the Fukushima Daiichi nuclear power plant bind to dust, which is how they travel through the air and eventually fall on the ground, according to CNN's chief medical correspondent Dr. Sanjay Gupta.

When cows eat contaminated grass, those particles can get into milk. Large surfaces of leafy veggies are at risk because they present a greater surface area for the particles to fall on; that's why several green vegetables can no longer be exported from certain areas near the nuclear power plant. Still, levels detected so far pose little risk, Gupta said. And so far there is no contamination of beef in Japan, the government said Friday.

Radioactive particles disperse the farther they travel, so by the time they get to the United States from Japan they are not concentrated enough to pose any health risk. The state of Washington and California have both reported low levels of radioactivity in milk; however, this milk is safe to consume, experts say.

And how about what that water might do to fish? If you're still craving sushi, it seems that, unlike after the Gulf oil disaster, there isn't as much concern about the safety of fish from Japan, Eatocracy reports. Fishing in the prefectures near to the nuclear plant - Fukushima, Miyagi and Iwate - has been suspended since the March 11 earthquake and tsunami, which makes it less likely that tainted fish will reach the market.

But there is justified concern for the health of the Japanese workers who are struggling to control Fukushima Daiichi, and getting exposure to doses of radiation far higher than the general public. While they are probably not experiencing any health effects right now, their long-term health should be monitored, experts say.

      The sad thing is, people will ignore what you said because they feel your insulting them. In reality your right. The media and politics are ruining this country. All they do is divide people and make them argue. They should be focused on the major points of what needs to get done instead their arguing.

      This article is so much crap. For one thing all they discuss is iodine-131 which is probably the least harmful owing to its short half-life. There are many extremely dangerous and toxic radio-neucleotides not discussed, or even acknowledged that would be giving us plenty to fear. The American sheeple are being systematically lulled into thinking there is nothing to worry about. The fact is, might as well not worry. Not a thing you can do about it anyway. As big a waste of time as worrying that you are going to die someday. Oh, there is one thing, you could be raising hell about the fact we have 104 nuclear time bombs in this country. And to go along with those, about 150,000 tons of spent radiaoactive fuel we still haven't found a home for.

      If the Romans had built nuclear power plants we would still be struggling with how to handle the waste they produced. Nice job for you kids to worry about.

      I would be more worried about the hundreds of aging nuclear weapons in the country (and other countries) than about the nuclear power plants. Those weapons were originally designed with a 10-20 year lifespan, and many of them have been sitting around for 60+ years. At least the power plants were designed to last 40 years from the beginning...

      Also, if the Romans had built nuclear power plants, we would all probably still be using them, just like we still use a good number of the roads, bridges, aqueducts, fountains, and bath houses they built.

      Right now, they have a choice, let the plant completely melt down and the spent fuel catch on fire and possibly melt OR dump the slightly radioactive water into the ocean so that they can pump other water into those tanks. It's THAT simple of a choice, no choice.

      Press responds to hits. If stories get web views, there will be more hype and subsequent stories on that subject. CNN and all those news networks are putting out stories of fear (as the news always does) because people click on that. The masses seek out reasons to be afraid. We seek out tragedy and horrible things, especially if they could in any possible way tie back to us. This isn't someone's "fault", it's human nature and includes the audience as well as the press. You DID just click on this story, read at least some of it and take the time to reply, didn't you?

      Agreed. Too long has the oppressive sun held dominion over us. Has everyone just magically forgotten the hundreds of years it took to dethrone the sun as a god? And even then we had to agree to make it the center of the solar system. That, and it continued to claim cancer victims in tribute to itself, in direct violation of countless international laws! This has gone on too long. It's time to finish the sun once and for all.

    What part of food chain is unclear? Pretty sure it works the same way today as it did in early March.

    The little organisms et the minerals and microscopic animals in the shallow water, then fish eat the little organisms and small animals, then bigger fish eat the little fish, then we eat the big fish.

    Last time I checked, sea life did not obey no swimming, fishing, or drinking signs posted within a mile of the shoreline. I am also pretty sure that they do not know the difference from Iodine's 8-day half-life and Cesium's 30 year half-life.

      You inject small amounts Cesium 30 every single day already. As long as it does not go above a certain amount your body (which evolved in an environment where this is an issue, i.e. the earth) is more then capable of dealing with it.

      Neeneko.... Yeah, we INGEST cesium every day, true. This is normally done in a salt form as natural cesium is similar to potassium and very stable. Cesium is atomic number 55, not 30; of course we are not talking about this element, rather we are talking about the man-made Cs-137, a highly radioactive and toxic isotope that takes 30 years to even become relatively safe. The levels of Cs-137 in the spill water coming out of those reactors (which by the way is about the only place you can get this isotope) is the problem. As a salt, it is taken-up as easily as potassium chloride or sodium chloride in tissue.... that is where my previous opinion comes into play. We are talking about two very different Cesiums here and the latter, 137, is the problem.

      It's stupid to compare the amount of radioactive sea water with the amount of current sea water, because it does not actually show how much radiation is being dumped. If the density of the radiation in the 11,500 tons of radioactive sea water is low then it will have much less of an impact. However if it is high then those same 11,500 tons stands to be a much greater threat to the surrounding environment.

      @Ryan: I'm afraid the dilution example you're citing isn't stupid – it's arithmetic. No matter what the concentration of the solution that has leaked into the Pacific Ocean, that concentration will be diluted by that factor indicated (assuming the math is correct).

    All this talk of the "short" half-life of Iodine-131 and very little talk of the 30 year half-life of Cesium-137 and Strontium-90 and absolutely no talk of the 24,200 year half-life of Plutonium-239. Natural selection will be forced to take its course and will probably evolve humans to look like lizards with thick skin to handle the high background radiation. We probably won't have to worry about over-population of the planet when the human species becomes sterile in a few generations.

    • An actual nuclear expert

      The reason the media talks about the shorted lived I-131 so much isn't because of a giant conspiracy to avoid other nuclides, as many imply. The shorter the half-life, the more radioactive a material is. Thats how radioactive decay works.
      Furthermore, I-131 is stored in the thyroid. Pu-239 is not, since our bodies don't "know" what it is.
      Also, Pu-239 is not very dangerous. It primarily emits alpha particles, which travel only a centimeter in air, and can't penetrate the skin. Since Pu-239 is very dense, very little of it's radiation even escapes the material.

      Even after this "catastrophe", nuclear power is FACTUALLY safer than almost everything. Low levels of radiation (below 1000 millirem) are NOT scientifically proven to be harmful. This is a fact. The "nuclear industry" didn't secretly make this up. They chose the legal limits on completely arbitrary grounds just to have a limit that seems reasonable.

      I find it interesting that people are so worried about the radiation, and not the actual earthquake + tsunami that has killed thousands.
      If I was living next to a nuclear plant and a giant earthquake happened (9.0 magnitude is HUGE), should I be worried about the low levels of radiation, not scientifically proven to be harmful, which occur, or should I be worried about my house falling on top of me?

    I am so tired of these people who are so brainwashed into believing that everything is ok. This pollution "isn't that bad". Give me a kit-kat. The oil leak in the gulf wasn't bad and then millions of birds and fish started dying out of nowhere. Dolphins started washing up on shore. Is fire the answer? I'm sure it has its downsides, but instead of pushing capitalism, technology and war down our throats, our collective governments should be responsible. However, we know they will not. Man cannot govern Man and we will be blessed when The Light returns to govern the world. Repent.

    Don't believe media articles telling you that there is nothing to be concerned about all this radiation spilling into the ocean, when has this ever occured in human history. And do we really know the likely outcomes, I don't think soo!.

    This reporter is just awful to pretend all is well – she probably is on the Board of Directors for General Electric – obviously in their pocket – please everyone in the US stand up to our government and DEMAND NO MORE NUCLEAR – it is bad for the world and humanity – I am saddened to read this article and know she is so ignorant about the facts and harmful nature of the radiation. She should be ashamed of herself – I wish she would go and work for a schucky magazine where lies are fine and fun to read – but to hold herself as a journalist is really wrong.

      No more nuclear! No more oil! No more coal! No more pesticides! No more inhumane cattle/pig/chicken farms! No more electricity! No more .... Yeah. Renewables are not ready to take over the power needs of this country, let alone the world. If you want to reduce dependency on these "evils", get rid of your computers, your TV's, your gas guzzling SUV and all of the little modern things that have blessed our lives over the last 100+ years. Aren't ready to do that? Didn't think so.

  26. Hi there.

    Don't get too upset with the fear mongers. They can't help themselves. Ignorance + a natural disposition towards expecting the worst of everything can manifest some pretty bizarre responses.

    Please educate yourselves.

    somehow, this is hard to believe. I think the government is lying to the public again. These are toxic chemical, although it is true that a small amount of it is not harmful but they add up faster than you'll recognize. I guess we don't have to wait until Dec 31 2012 to see dooms day because it's already here.

    The whiners need to be quiet. People like me are making a lot of money thru nuclear power investments. You people's bodies can handle a lot more radiation than these nuclear accidents are adding to your bodies. Quit whining because some of us are making good money. Your bodies can stand a lot more radiation than their getting now because some of us need the money. So quit whining about a little extra radiation getting into your body. Just shod op!!!

    Just remember that radiation that leaks out now will be with us for 500,000 years and it adds up in your body. It's a fact that every human body on the planet has a little bit of the radiation from Chernobyl in it.

    Sanjay, I've personally experienced Sahara Desert dust storms depositing a thick layer of sand on the island where I lived in the Caribbean thousands of miles from North Africa. Dust + radioactive particles can travel across oceans in dense formation. Secondly, radioactive particles are not healthy to ingest in any concentration. Any detectable radiation is too much. These sources challenge the myth of "safe levels" of radiation particles in our food and milk.

    People hyping this do everyone a disfavor – while this is not ideal there are instances of much worse contamination being released into the ocean or worse into populated areas. Fear is not science or caution. Its international and always leads to problems.

      Radiation apparently doesn't hurt the ocean, so we shouldn't have an issue dumping other far less dangerous chemicals into the ocean. Quit hyping that pollution is bad when obviously it isn't. Didn't you read the article? It all gets diluted.

    A quick note about the half-life of Cs-137...

    The radiological half-life is 30 years. The biologic half-life is about four months (110 days). That means that if you ingest some Cs-137, half of it will have left your body by natural processes in 110 days. After one year (3.3 biologic half-lives) the Cs-137 in you body will be reduce by about 90%. And during that one year in your body only a tiny fraction of Cs-137 will have decayed and caused your body damage. Remember, it takes 30 years for half of it to decay, so in one year very little decays. And it only causes damage when it decays.

    So stop panicking and read up on little science.

      im not religious but hopefully everybody reads the following... fema and department of homeland security are going to conduct nle 2011 which is an exercise that "simulates" an 8+ magnitude earthquake on the new madrid fault and it is scheduled for may 16 – 21 2011. victor may be right. i also need everybody to think about if you put a one million watt powered subwoofer on a fault line, what do you think might happen? its 2011 people. the u.s. government can cause earthquakes. again think powerful subwoofers.

      @ david: If I understand your concern correctly, you are misunderstanding what a FEMA NLE is. "Simulating" an earthquake does not mean that the government is going to cause an earthquake.. think of it as basically a large scale (and fairly expensive and very complicated) fire drill. They don't create an earthquake for the test any more than they actually set fire to all the schools/businesses/ect. in which fire drills are conducted.

    This article fails to mention how radiation becomes concentrated in food by the time people get around to eating.
    You aren't just eating one exposed fish you are eating all the contaminated fish it eat and all the contaminated fish those fish ate and so on and on so that by the time it reaches your dinner table you can be exposed to many times the amount of contaminates that are measured in the water.

    I don't understand how they can be so sure that there is no danger caused by dumping radioactive materials into the ocean. Who cares that fishing in the neighborhood of the reactor has been suspended? Don't fish swim from one place to another? So they swim from the reactor to a northern city where they are caught, packaged, and shipped to the USA for us to eat. When it feels like you are being lied to, you probably are.

    "Fishing in the prefectures near to the nuclear plant – Fukushima, Miyagi and Iwate – has been suspended since the March 11 earthquake and tsunami, which makes it less likely that tainted fish will reach the market."

    Don't worry guys, it's OK, the fishing has been suspended so there's no reason to panic! How can anyone buy this garbage. I am panicking already for the wildlife that has had to suffer through this. But don't worry, we just won't fish there and everything will be hunky dory?

    STFU and don't tell ME not to worry! How dare you destroy the planet and then look the other way.

    Wow, another great article virtually devoid of any information that would allow people to make there own decisions. Basically the author said, trust me and Dr. Gupta everything is fine, instead of providing any information that could enlighten the reader. As an example, she could have mentioned what US organization (the USDA, FDA, etc), sets limits for radiation in food, what they deem to be safe, what the UNITS of measurement actually mean, what the level of radiation is, the species of radiation, and the half life of said species. Instead, Ms. Landau seems to assume we are stupid and can't process real information and make up our own minds when presented data. It's indicative of most reporting I've seen on this incident, and indicative of how poor a job the US media does at actually informing the populace. Ms. Landau, take your lumps and write a better article next time – trust us, we'll appreciate more information,

    If one gets old enough, one has seen it all before. This article reminds me of the "radiation is our friend" propaganda puit out by the media and U.S. Government dring the 1950's when the Cold War began. School choldren were told that they could shelter freom a nuclear attack by hiding under their desks. Such under-the-desk, take shelter drills were regularly practiced.
    An article in the New York Times two days ago really let the cat out of the bag. It said that since Three Mile Island, countries with civilian nuclear reactors had developed "codes" which could use measurements after a nuclear incident to ascertain the type of damage and the magnitude and effect of the release of different isotopes of radioactive material. So far all this data and information has been carefully witheld from the public.

    What total BS. This water should have been stored like spent fuel rods. And radiation varies based on the type. If any of this is from plutonium, it will do much more damage as that radiation sticks around....passed right up the food chain. Do you dump your used motor oil in the ocean, NO. So you sure a hell should't drop this in the water either. First they work hard to find where the leak is because they don't want any more going into the ocean. Then when they have a bunch more, they do it on purpose. WHAT IDIOTS!!!
