Wildlife Defies Chernobyl Radiation 612

Posted by CowboyNeal from the comeback-trails dept.
An anonymous reader writes "The BBC reports that wildlife has reappeared in the Chernobyl region even with high levels of radiation. Populations of animals both common and rare have increased substantially and there are tantalizing reports of bear footprints and confirmed reports of large colonies of wild boars and wolves. These animals are radioactive but otherwise healthy. A large number of animals died initially due to problems like destroyed thyroid glands but their offspring seem to be physically healthy. Experiments have shown the DNA strands have undergone considerable mutation but such mutations have not impacted crucial functions like reproduction. It is remarkable that such a phenomenon has occurred contrary to common assumptions about nuclear waste. The article includes some controversial statements recommending disposal of nuclear waste in tropical forests to keep forest land away from greedy developers and farmers"

      No. Every generation tends to get rid of bad mutations. It's called natural selection. While a few alarming but non-fatal mutations will occasionally be expressed, most mutations will simply result in reduced fertility due to terminated abnormal pregnancy. But wild animals are generally fecund enough to make up for the losses.

      Consider that the average human conception has about three dangerous mutations even without Chernobyl. Why aren't we oatmeal? Because a goodly percentage of conceptions never make it past the blastocyst stage due to excessive nasty chromosomal damage, while we lucky survivors had fewer.

      Chernobyl happened 20 years ago. Some species, like mice, have probably had several dozen, if not hundreds of generations. Even dogs rarely live 20 years, and I'd imagine wolves to be the same. If that's true, assuming that a wolf first reproduces on average at the age of 2, there have been 10 generations of wolves after the Chernobyl accident. In any case, there has been time for several generations to be born.

As for us, we figured we have no plans to ever have any kids anyway and so we signed up for the waiting list. We got in on a cancellation and ended up on a bus full of senior citizens with our tour guide, Ernie, with decades of experience in the atomic testing program. Ernie tended to downplay the safety implications of the testing done on the site. Well, he did mention the leaks and accidents but his voice dropped really low whenever he talked about them... he used the phrase "well, I make no bones about it". Whenever Ernie's voice dropped, you could look out the window and the bus would be passing a fenced area along the side of the road with big scary RADIOACTIVE signs at regular intervals fighting to stay visible above the grass. Ernie was a trip. If you are interested in a tour of the Nevada Test Site go soon while Ernie is still alive to be your tour guide.

    Not all damage to DNA from radiation is harmful. Cells have repair systems and can quickly repair breaks in DNA, with no long-term cellular consequence. Alternatively, the repair may not return the DNA to its original form, but may retain its integrity. If cellular damage is not repaired, it may prevent the cell from surviving or reproducing, or it may result in a viable but modified cell. These two outcomes have different results, leading either to deterministic or stochastic effects [Court of Appeals, 1999, pp. 37, 38].

      Come on. Is anybody really surprized? Scientists for years were questioning the necessity of Chernobyl evacuations and creation of the excluded zone (some evacuations were necessary but the zone was generally too broad). The stress due to evacuations was more harmful than the radiation. In the official UNSCEAR report [unscear.org], these voices were included. People can safely live there now so why not the animals? The radiation level in the "zone" is no more than 10mSv/year. Although it is above the average world natural background radiation (2.4 mSv/year), there are a lot of places where people receive larger radiation doses without ANY harmful effects including Ramsar in Iran, where the doze is 260 mSv/year [uic.com.au], 26 times larger than in the Chernobyl zone.

      It is known (although ignored in strict radiation regulations) that the same dose received in short time is much more harmful than the dose received during longer times. It is probably because the cells have repair mechanism that can cope with small damage over long time while cannot efectively repair large damage in short time. There are even indications that small doses can be beneficial [wikipedia.org] by "training" the repair mechanism.

    It reminds me of the large scale experiments done on plant breeding [1] where radioactive material was placed in the centre of a field of crops, and favourable mutants were selected. I love telling this story to anti-GE people, who probably eat plant products produced as a result of these experiments done predominantly in the 1970's. At least with GE only a single well studied change is being made.

    Since these organisms have such short lifespans, there have been ample generations since the nuclear accident for the organisms to go locally extinct or mutate into different species. But, that has not been the case. These local populations have continued to survive without deleterious effects on the population level.

    Populations of organisms with longer lifespans may take longer to recover to pre-blast levels (although from the sound of the article and my previous knowledge the opposite has occurred) and may experience a genetic bottleneck effect (which may be countered by mutations), but genomes are resiliant and it is unlikely that the populations would never recover.

    • Sure enough, life adapts when it has to.
    • The current radiation levels are probably a lot lower than the levels when the area was freshly sprayed with molten core and irradiated particles.
    • The radiation isn't *that* bad. We'd consider it wildly unacceptable if 1 in 10,000 people died over the course of 5 years. Animals won't notice.
    • Getting rid of humans is *great* for wildlife.

    So why are we surprised that any of this is happening?

    It has been postulated that life wouldn't exist the closer one gets to the center of the galaxy because of the ambient radiation, and, in fact, a system with life would need to be positioned the same as our solar system is to avoid the radiation. But if life on Earth can adapt to high radiation so quickly, how much that does that improve the chances of life near the rim of the galaxy where the ambient radiation is higher but not so incredibly high?

    Think about the natural causes of mortality for wild animals, are radiation effects going to have a substantial impact on populations? Cancer is largely a disease of the old.

    The article pointed out that the radiation has kept humans out, and allowed wildlife to thrive.

    ...He went on: "I have wondered if the small volumes of nuclear waste from power production should be stored in tropical forests and other habitats in need of a reliable guardian against their destruction by greedy developers".


    Let me assure you, this is no protection against greedy developers. In our own city (Chesapeake), there is a section called Deep Creek that had a dump. Said greedy developers wanted to develop said dump; local residents fought it on the basis of contamination and danger to homeowners. Said developer waited twenty years until said homeowners no longer had the strength or will to say said statements before the zoning board. Then the City Council quietly gave permission, after which a housing development was built upon said dump, and after that homeowners discovered trash and contamination under their houses. Said houses had to be destroyed, said developer profited and moved on, said city council bided their time, and in the end only the purchasers were hurt, as far as I know. Said greedy developers will not be stopped by so minor a thing as radiation in the way of their profit.


    Enough said.

    To give a reliable overview, you'd have to track ALL the animals there and observe the population. Here is what you would find:

    Some die instantly at the blast.
    Some die within the next hours.
    Some die within the next days/weeks/months.
    Fertility goes DOWN, but those THAT have offspring will have a higher chance to raise them to maturity (less competition).
    Again, of those some will die due to mutation.
    Some will have a shorter life expectance. As long as they mature and can raise at least one generation of offspring, it's not so important.
    Also keep in mind that quite a few animals CAN only raise one generation of offspring, they die after giving birth/laying eggs.

    Bottom line, of course animals will survive, as a group. Humans would too, the body count would be incredibly high and the chance that YOU, as an individual, survive, is incredibly small. But as a species, you can fairly reliably survive a nuking.
