American Honey Is Radioactive From Decades of Nuclear Bomb Testing (vice.com) 133

An anonymous reader quotes a report from Motherboard: The world's nuclear powers have detonated more than 500 nukes in the atmosphere. These explosions were tests, shows of force to rival nations, and proof that countries such as Russia, France, and the U.S. had mastered the science of the bomb. The world's honey has suffered for it. According to a new study published in Nature Communications, honey in the United States is full of fallout lingering from those atmospheric nuclear tests.

For the study, researchers collected honey samples from more than 100 hives and soil samples from 110 locations across the Eastern United States. The scientists found elevated levels of cesium in both the soil and honey samples. "While most of the radiation produced by a nuclear weapon detonation decays within the first few days, one of the longest-lived and more abundant fission products is [cesium] , which has a radioactive half-life of 30.2 years," the study said. Previous research after the Chernobyl nuclear disaster identified elevated levels of cesium in European honey and pollen. The good news is that, according to researchers, most of this honey is probably safe for humans to consume. "While the concentrations of [cesium] we report in honey today are below the...dietary threshold level of concern observed by many countries, and not evidently dangerous for human consumption, the widespread residual radiation...is surprising given that nearly 2 half-lives have elapsed since most of the bomb production of [cesium]," they said.
Interestingly, the researchers "also found an inverse relationship between the amount of potassium naturally occurring in soil and the amount of fallout found in honey," the report says. "Southern states contained three times the amount of fallout that the northern states did. Southern soil doesn't contain much potassium while soil in the north is rich with the stuff. While this honey is probably safe for human consumption, it may not be for the bees who generate it."

        So cesium (and anything else radioactive) gets LESS radioactive over time, not MORE. By necessity - releasing energy means that energy isn't in cesium anymore.

        Which means, bees today are getting far LESS radiation from it than their parent, grandparents, great grandparents, going back 650 generations of bees. They've done alright for 650 generations with MORE cesium radioactive. What makes you think that LESS is suddenly going to be a huge problem?

          Duh. The cesium in honey doesn't come from the bees or their parents. Cesium in honey comes from the pollen they collect in the wild. This shows that cesium is lingering in the environment even decades after the nuclear bomb tests.

        • In a very simple understanding you may be correct, however we don't live in a simple world. The fact that cesium shows up in honey at all shows that it's still there, since cesium decays into a metastable barium when it spins off that gamma ray. And since the bee didn't just go pick up some cesium off the ground, it's been absorbed by a plant that the bee grabbed some nectar from, probably in replacement for the potassium the plant was really looking for.

          insects are tougher than us when it comes to radiation though

          It comes from the complexity of the DNA I believe. Insects are far simpler biologically and thus their DNA doesn't code for as much and is much more redundant, thus can tolerate a lot more errors before failing. Insects also generally have very short lifespans measured in days or weeks so the effects of damaged DNA might not have time to manifest. And given the reproduction of insects is often only by a queen or so, it also means if the insect's DNA is damaged, it's not propagated onwards unless the queen or her male cohorts are affected.

          Among insects, cockroaches would be the first to die in a nuclear blast - they are complex insects.

          • Just want to say, I think "proximity" beats out DNA complexity or even IF you have DNA when it comes to the lineup against a nuclear "blast".

      I understand some instruments used for carbon-14 dating are built with a radiation shield consisting of a chunk cut from a WW II navy gun barrel. That's because the steel, with the carbon in it, was smelted before the atmospheric nuclear tests released enough carbon 14 to make modern steel unsuitable as a radiation shield for this purpose.

    From the study,

    Using low background gamma spectrometry, we found detectable 137Cs (0.03Bq 137Cs kg1=105.94 atoms tablespoon1) in 68 of 122 distinct honey samples sourced from North America.

    One becquerel is one decay per second.

    Here's the unavoidable banana equivalent.

    Since a typical banana contains about half a gram of potassium, it will have an activity of roughly 15 Bq.

    Check my math, please,
    The average Florida wildflower honey had 3.4 Bq/kg, so you would have to eat 4 kg of that honey to equal one banana.

    "the widespread residual radiation...is surprising given that nearly 2 half-lives have elapsed since most of the bomb production."

    It seems that after reviewing the comments here, the actual radioactive levels are being compared to a single banana, and thus quite low.

    I'm more focused on the comment above. Unless we truly don't understand the half-life of cesium, why exactly do we feel this radiation, was from nuclear testing? The article states "cesium", but my understanding is there are elements of that which occur naturally, and also elements that are the result of nuclear activity (cesium-137). It just seems like if we're that far removed from nuclear testing, there might be another reason we're still detecting elevated levels today.

    We're almost 2 "half" lives removed, so what happens when that's 4 "half" lives? Or 8? We going to re-define the half-live of cesium, or perhaps stop pointing the finger at nukes?

    The other scary part about this, is colony collapse. Here we are almost 60 years after stopping massive nuclear testing, and we're just now starting to understand the impact on bees. I wonder what we ignorant humans would have done had we inadvertently nuked honeybees from this planet long ago? We talk a lot about the impact of that, and yet if we would have caused it, we would have been screwed. (We'd still be screwed.)

    We're damn lucky honeybees appear to be more related to cockroaches than we thought.

      I'm more focused on the comment above. Unless we truly don't understand the half-life of cesium, why exactly do we feel this radiation, was from nuclear testing?

      This one is actually pretty straightforward. There's hardly any natural production of cesium-137 - only trace amounts come about from the natural decay of uranium (238U). On the other hand, we know that cesium-137 is an abundant product of nuclear explosions (and accidental releases from power plants). The radiation produced by 137Cs is well characterized: gamma rays with an energy of 0.6617 MeV. You could think of that gamma emission as a characteristic "color" of the decay: if you detect that energy/color, it almost certainly came from cesium-137. And if you find it out in the world (as opposed to near the nuclear power plant), it is almost certainly left over from the development of nuclear weapons.

      I suppose what the researchers found surprising isn't that there's still cesium-137 left over from the atmospheric tests of the 50's and 60's - you can find it the world over if you look - but that it was being taken up and concentrated in plants and then, by extension, in honey.

    • One half life is only halving the quantity of initial element. So assume you started with 1 g of 137Cs spread over a field due to nuclear explosion testing (actually quantity is lower it is just an arbitrary number to show an example), after 1 half life, there is only 0.5g, after a second there is 0.25g. The activity by that point would be divided by 4 (so our 1g had 3.25*10^12 so the 0.25g will have about 8.10^11 Becquerel activity). This is STILL the same Cs from the start so from our initial testing. Whe
    • The other scary part about this, is colony collapse.

      Colony collapse is the consequence of using neonicotinoides. All other factors contribute a bit, but none as much as those bugkillers.

      That you read so much about other factors is because the producers of neonicotinoides decided years ago to fund an avalanche of studies that should lay the blame on everything but neonicotinoides. It is similar to what happened with the cigarette industry a few decades before. They use science to bury the really relevant insights in order to keep raking in their profits.

    According to Fig.5 in the referenced paper, the radiation dose from cesium was no more than 3.5 times background potassium radiation, and in 90% of samples was below background radiation. In 2/3 of samples it was at least 10x lower than background radiation.

    Now, background radiation itself varies. They found the highest cesium where there was the lowest soil potassium, meaning... 3.5 times the *lowest* background radiation.

      Depends on where you are sampling, and when. There were lots of atmospheric tests, and that fallout was (after years) distributed pretty uniformly worldwide.

  • I downloaded the paper's supplementary datasheet (excel file) and for context the radioactivity of the cesium-137 that is the focus of the paper is 1 or 2 orders of magnitude below the radioactivity from naturally-occurring potassium-40 in the honey. So absolutely no cause for health concern.

    Interestingly, the researchers "also found an inverse relationship between the amount of potassium naturally occurring in soil and the amount of fallout found in honey," the report says. "Southern states contained three times the amount of fallout that the northern states did. Southern soil doesn't contain much potassium while soil in the north is rich with the stuff.

    This strikes me as a shining example of correlation without causation:
      - The soil in the southern states has lower potassium levels than that in the northern states. This is due to geologic and weather factors over a past interval on a geologic time scale.
      - The fallout is higher in the southern than the northern states because the US atmospheric tests were conducted primarily at the Nevada Test Site, at their approximate latitude. The prevailing winds were from the west, and the tests were generally done when the wind was in its usual direction, toward Indian reservations and Mormon areas (such as St. George Utah), and times when the wind was toward Los Vegas were especially avoided.

    So the correlation appears to be a coincidence of geography, rather than a sign of some underlying mechanism.

    • Cesium and Potassium are both Group 1 cations so they compete for the same biological substrates; the more famous example of this is strontium and calcium in Group 2. Lower availability of potassium means a higher likelihood of cesium being incorporated into a biomolecule. I agree with you that it's more likely related to fallout patterns, but the paper is about apparent concentration of cesium by biological processes. It's not a 'magical' mechanism.
