Effects of radiation on birds in Chernobyl

Post by Earth Cries on Sun Feb 06, 2011 12:19 pm

Chernobyl birds are small brained

Would like to see studies of the other animals in the area.

Great article. I agree.. there should be more studies:)

it shows you just how long lasting the effects are Sad

Can you imagine if that happened in one of the major cities such as Tokyo!

I read an article a few weeks ago saying that the fallout is still present in the reindeer and caribou in the northern countries. And they are still trying desperately to repair the concrete shroud around the blown reactor. Also saw a documentary about some of the older people that refuse to leave the hot zone. They say they are old anyway and they won't leave their homes. Their families come to visit very short periods of time because the rad is still so high it's dangerous for them. The old ones say they have nothing to loose by staying.

Here's an article from 2 years ago about the animals also about the children living near there:(

Yes you can imagine that : http://www.hiroshima-remembered.com/

As a white coat i can tell you that the lenght of the aftermath depens on the matter that is used and the place where it explodes, the two boms on japan supposed to have used all their matter and the one on hiroshima was an aerial burst. An aerial burst doesn't contact and activate debris that is blown into the atmosphere like a surface burst. Henche chernobyl is about 700 years contaminated while nagasaki one week later, the dose would be only one millionth the original dose. With no radioactive matter left over and no contact, aerial burst, residual radiation levels fell very rapidly.


The chernobyl reactor exploded on ground level, activating the ground and surrounding area. The chernobyl reactor exeeded radioactive contamination by 100 times compared to the two on japan. Agricultural areas around Chernobyl covering nearly 52,000 sq. km, which is more than the size of Denmark, were contaminated with Cesium-137 and Strontium-90, with 30-year and 29-year half-lives respectively.

Is it true that the common cockroach was the first creature to return to Chernobyl?

I doubt it, other than humans, the native wildlife never left. There have been a number of studies showing that the native wildlife population has in fact greatly increased since the accident. Without humans to keep the population down plants and animals have both done well.

I wonder if the reduced brain size has more to do with the lack of competition than the radiation. When food is plentiful, even birds get lazy. Just a thought...

A new kind of mushroom that eats radiation showed up in Tschernobyl.

Shocked

Wow!

From the article:

...findings of melanised fungi, happily congregating in the cooling pools of functional nuclear reactors, and by studies of dark, 'radiation-seeking' fungi, purposefully growing towards radioactive particles in soil, particularly around Chernobyl.

The team looked to the example of photosynthesis as a model, said Casadevall. If plants can use the green pigment, chlorophyll, to absorb energy from the Sun and produce a usable form of chemical energy, they reasoned, fungi might be able to use their melanin pigment and radiation energy in a similar way. They even devised the snazzy moniker, 'radiosynthesis', for the process.

I was actually watching a show on that not too long ago. It is very green and lush with a diverse group of animals. They are all irradiated and have shorter lives because of it but no extra limbs to be seen. It was quite beautiful.

The smaller brain has baffeld reasearchers. Bird that migrate have maller brains than birds that stay in one place/area. "the brain is an organ that consumes a lot of energy and develops slowly and this can be too costly for migratory species which must travel far and have little time to reproduce. At the same time, the reduction in brain volume could also be caused by a decrease in cognitive functions no longer useful to migratory species. For birds that travel a lot, exploring their surroundings produces more costs than benefits since the information which is useful in one place is not necessarily so in another.
http://www.sciencedaily.com/releases/2010/04/100429082854.htm

Another atricle, Migrating Songbirds Learn Survival Tips On The Fly, indirectly supports that thought. The learned dangers at the start of the migration are no longer needed and therefore thrownaway, brain shrinking, after the migration they learn the new dangers from other birds, brain growing.
http://www.sciencedaily.com/releases/2008/06/080625105621.htm

Other studies show that the common cockroach is, at least in terms of nuclear survivability, a wimp.
