Cockroach breeds like the German Cockroaches can withstand exposure to 100,000 rads.
How Can Roaches Survive a Nuclear Bomb?
From research, it has been proven that cockroaches can withstand a large amount of radiation – like the 1945 Hiroshima bomb. That explains why many of these bugs survived the 1954 blasts.
Now, does that mean cockroaches are indestructible? Of course not! A test carried out by Mythbusters revealed that some German roaches were exposed to various levels of radiation to see how much it took to finish them off. It was a lot.
Humans typically will kick the bucket when exposed to relatively small amounts of radiation. In fact, an average human will succumb to under 1,000 rads – but these cockroaches were defeated by exposure to 100,000 rads.
You should know that a nuclear blast isn’t the only danger of radiation; there’s also heat and impact. The Hiroshima bomb was said to have released 10,300 rads into the air – enough to kill a human, but not a roach.
heir experiment started with a baseline of 1,000 rads, and gradually increased in increments of 10,000. The group of roaches were able to survive up to 100,000 rads before succumbing – which is astounding. For reference, the bomb dropped on Hiroshima in 1945 was around 10,000 rads.

Can Cockroaches Really Survive A Nuclear Explosion?
Scientists tested German cockroaches to see how much radiation they could withstand. The experiment only tested how many days the cockroaches lived after exposure and not their ability to reproduce afterwards.
In order to determine their claim regarding the cockroach’s ability to live through a nuclear war, the Discovery Channel tested three levels of Cobalt-60 metal, a radioactive element.
Mythbusters creates a test with cockroaches, humans and radiation. Cockroaches has the ability to withstand lethal doses of radiation than humans.
A human can produce viable eggs following 5 rems of radiation, but cockroaches are much stronger than humans and can handle lethal doses of up to 105,000 rems.
For humans, a dose of 800 rems is lethal, but for a cockroach, the lethal dose is 67,500 rems, which could be equivalent to that of a thermonuclear explosion.
Researchers have proven that cockroaches have a considerably higher tolerance for radiation than humans, with most of the meaning to their 10-12 pair of chromosomes

How Cockroaches Survive a Nuclear Explosion?
Humans are sensitive to ionizing radiation because of the constant changes going on in our cells. Cockroaches, which only moult about once a week and have a 72-hour growth cycle for cells, can better withstand ionizing radiation.
Nuclear explosions can damage life in a variety of ways, including from the initial blast and from the tremendous amount of heat and radiation. However, while a nuclear blast can be fatal to life, insects such as cockroaches can survive if they’re protected.
This is because cockroaches are known to eat virtually anything, not just meat but also things like garbage. That being said, it should be noted that insects can only live for so long before they inevitably die too.
How do cockroaches survive nuclear Radiation?
Cockroaches have an interesting ability to survive in adverse conditions. Their ability to resist radiation and corruption makes them ideal candidates for studying how organisms can withstand the intense heat and pressure of a nuclear explosion.
While cockroaches are not typically studied in detail during nuclear bomb tests, their resilience has led to some interesting discoveries about how organisms function in extreme conditions. For example, scientists have learned that cockroaches exhibit a high degree of adaptability, which helps them survive the initial blast and subsequent firestorm.
In addition, cockroaches are able to scavenge food and shelter after the explosion. This behaviour is likely due to their advanced sense of smell, which allows them to locate food even after the air has been poisoned by radiation. Cockroaches also tend to aggregate together following an explosion, forming large colony balls that provide protection from radiation and fire.
So, Will a Nuclear Heat Blast Kill a Cockroach?
If a roach is instantly exposed to a nuclear blast, the heat from the detonation will kill them instantly.
What can you do to prevent cockroaches from surviving a nuclear explosion?
There is no one-size-fits-all answer to this question, as the best way to prevent cockroaches from surviving a nuclear explosion will vary depending on the particular circumstances. However, some general tips that may be useful include:
1. Keep your home clean and free of debris. This will make it difficult for cockroaches to hide and survive a nuclear explosion.
2. Keep your food storage areas clean and dry. Cockroaches are attracted to moist environments, so keeping food storage areas clean will help keep them away.
3. Store food in sealed containers. Cockroaches are unable to digest many types of food, so keeping food in sealed containers will help protect it from them.
4. Install insecticides and/or traps in areas where cockroaches are known to congregate. Insecticides and traps can be effective at killing cockroaches and may help to reduce the number of these pests in your home after a nuclear explosion.
