No creature has a chance of surviving in the focus of the bomb, but cockroaches have a good chance of surviving the fallout
First and foremost, nothing can survive the intense heat that prevails in the affected area. For example, the 15 kiloton bomb that was dropped on Hiroshima ignited a firestorm at a temperature of about one thousand degrees Celsius, which destroyed everything in a radius of about two kilometers. However, the roach has a decent chance of surviving the fallout that follows.
The average cockroach can withstand radiation of 6,400 rads [an official unit of measurement for radiation exposure]. The lethal dose for humans, on the other hand, is only 500 rad - equivalent, more or less, to 42 full CT scans at the same time.
One theory attributes the cockroaches' resistance to the weekly shedding of the larva, during which the rate of cell division is about half of normal. In mature individuals, the rate of division is even lower. Since radiation causes most of the mutations in DNA that is replicated - a phenomenon that occurs mainly in dividing cells - the slowing down of the replication rate protects the cockroaches from radiation.
However, even cockroaches cannot compare to the bacterium Deinococcus radiodiurans, which is almost completely unaffected by radiation. In 1956, scientists discovered that the organism thrived in a can of spoiled meat that had received a dose of gamma rays. In subsequent studies, it was discovered that the bacterium was able to survive even a dose of 1.5 million rads. It is likely that this is enough to survive a 1.2 megaton bomb - which experts estimate is the largest in the US ammunition stockpile.
Scientists still do not know what DNA repair mechanism allows the bacterium Deinococcus radiodurans to withstand such high levels of radiation. One of the possibilities is that at the moment when the bacterium's DNA chains break, proteins protect the ends of the chain for a long time until it comes back together (similar to the ends of a torn rope that are joined immediately, even before they have enough time to separate and move away from each other). If it turns out that this is indeed the case, the scientists may be able to offer a similar protein to human cells - which will be able to survive even longer than the cockroaches.

All in all, the human being is the most disgusting animal there is and the most annoying, better yet cockroaches..
The feeling of disgust is intended to deter us from things that have infectious potential
Look it up online
It is clear that God also created the cockroach (fixed for those who persist). After all, it is known that disgust is a basic emotion. And it needs to be evoked often even in such a modern environment. Without feeling disgusted, how can we be balanced? In my opinion, a more interesting question would be why the disgust was created in the first place, but that is already out of scope.
Very nice. The two most repulsive things in one thread. Jock and God. Thank you. And we'll move on to something completely different...
Elijah the prophet:
It is not God who created the GOK.
If anything then on the contrary.
Ami, maybe you can explain then why God created all this life???
to annoy us ??
In fact I didn't even say they shouldn't be investigated. Let them investigate, let them do what they want to do. This animal is disgusting. Her picture here in the science gives me strong feelings of disgust. I have a friend who is a doctor at BSH on the behavior of cockroaches after all kinds of electrical pulses that he gives them directly to the ganglia. He claims that it always amazes him how the reactions and behavior of the cockroach can be controlled, as if programmed, by those electrical pulses. He believes that on one level or another this is true for all animals. that with the right pulse in the right place you could make a conquering people, for example, love a conquered people and vice versa. It's all a question that a qualified electrician can answer.
All this still doesn't mean that the jock's nimble, hairy legs with its triangular head and light brown aren't nauseating.
Bye friends,

Hanan and Ami:
This is one of the cases where just making the claim proves it.
After all, Ami did not claim that cockroaches are disgusting cockroaches.
He claimed that cockroaches disgust him and there is no reason to suspect him of lying.
Your words - which are rational in this case - can convince Ami of what I believe he is also convinced of (even though he said the opposite - but it seems like a joke to me) and that there are many reasons to study the cockroaches even if they disgust him.
I still think they are disgusting
You are indeed right, my father. Most advertisements refer to cockroaches as "cockroaches" or "cockroaches"...
To be honest, the term "cockroach" is more appropriate since it refers directly to this insect and from my investigation, it may have come through the Yiddish way...
And so that at night time the discussion will be more scientific and no less interesting, since the matter of the macaque has already been brought up, as far as I know, the species of macaque monkeys are a type of macaque monkeys.
We will leave the jokes here (and they will probably remain long after us) and we will leave the ideological discussion to the articles about UFOs, when they are published...
The main thing - have a good week 🙂
There is a very nice site for learning different languages.
Here is what he presents in the chapter "Insects" in Hebrew:
http://www.languageguide.org/im/insects/he/
Our friend is in the second row.
Cockroach is not a slang word (slang when used in Hebrew, it is actually a slang word).
Cockroach is a standard word synonymous with cockroach.
Two responses to Hanan.
First thanks for the comment. I take every comment to heart and try to implement it.
However, the article is from an external source and I need to take action to correct it.
In this specific case, I will consult with other parties because I am not sure that the claim is accurate, because otherwise all Snow's advertisements should be changed as well as the inscription on all the insecticides.
post Scriptum. Is it possible that a monkey is called a macaque and not a cockroach?
In any case, I'm glad that not all debates in talkbacks are ideological.
In this case, yes Michael. In my opinion, a translation must be in a standard way and not in slang, even though it is incorrect.
What's wrong with standard Hebrew anyway????
Hanan:
So again everyone is wrong? Also the author of the article, both the authors of Babylon's dictionary and the authors of the Oxford English-Hebrew dictionary?
In all these places "cockroach" and "cockroach" are synonymous words. Having a monkey named "cockroach" doesn't change that. The name "cockroach" in this case is not a Hebrew word at all.
It can be argued that replacing some word with the word "fixed" can be read as "fixing" the article, but I assume that is not what you meant.
To Ami Bachar: Maybe visually they don't look very attractive, but these are the fastest running insects known to us and the most durable in all respects. That's why the increased importance of the research done on them.
And the author of the article please correct: "cockroach" is a monkey, the insect known to us as "cockroach" (which is a Russian word in origin) is called "American cockroach" in Hebrew...

In the article on "Bacteria and Radiation" that was presented here not long ago, there is actually a good explanation for the reason for the wonderful resistance of Deinococcus radiodiurans to radiation.

I'm sick of it! Hairy legs, triangular head, running and flying in a very disgusting way... Foy. How can you investigate a cockroach? Filthy creature! baa
