A nuclear blast or radiation is a real firestorm that nearly nothing can endure.
It is a controversial question of how do cockroaches survive radiation?
The cockroach has a tough exoskeleton i.e skeleton outside the tissues which preserves it from being harmed by radiation. The cockroaches have very limited water in their body so the radiation will not mess up a lot.
The reason behind the survive of cockroaches
The interesting fact is that cockroaches can withstand radiation exposure for days the amount of radiation that would ruin a human being in less than 10 minutes can be sustained by a cockroach, so next time you witness that roach, remember to leave a salute!
So simply in case, the world should cease by nuclear explosion radiation, there would have cockroaches as the new world residents.
To examine whether this doomsday situation has any support, the researchers subjected German cockroaches to three stages of radioactive metal cobalt 60.
They began with a baseline exposure of 1,000 radon element of cobalt 60, able of killing a person in 10 minutes, and 10,000 rads have the capacity to kill a person within a few minutes, and 100,000 rads will kill completely.
As a contrast, the bomb on Hiroshima released radioactive gamma rays at a force of around 10,000 rads. Cockroaches can withstand 10,000 rads, and half of the search subjected that the cockroaches were “alive and kicking”.
Normally, the cockroaches have a strength to resist extreme radiation exposure may get down to their simple figures and slower cell cycles. It can be also stated that the successful insect to cross along with the evolution.

The magnificent things to know about cockroaches:
Cockroaches belong to Arthropods species, they continue ionizing radiation in the period between molts.
There is a point of time between nearby molts when the cells of the arthropod’s body essentially stop dividing. There is no mitosis at this moment.
However, ionizing radiation has the greatest impact on cells during mitosis, when the cell is breaking.
So in the interval between molts, the arthropod is not significantly influenced by ionizing radiation.
Simply before a molt, cells have to dissolve very quickly. A fresh exoskeleton and new attachments have to be developed to replace those dropped during the coming molt.
So the speed of mitosis is very active just before a molt. Maybe at this period, ionizing radiation has its highest effect.
Roaches, on the opposite hand, only molt around once a week at most, which causes radiation’s window of chance to hit cells much narrower.
But if the radiation was strong enough, even these old critters couldn’t continue on.
It’s this protection, along with the factor of future evolution that will make cockroaches the best varieties to survive radiation fallout. It’s a somber and unusual thought, but if humankind does end in a nuclear war, it’s this part that gives confidence to the assumption that insects such as cockroach will acquire the planet long after we’re gone. Hope they will lead their life happily without us.
