Misconceptions

All through my life I believed that cockroaches could withstand anything. But why wouldn't I? That's what I had always been told, and trained to believe. Yet I was way off. After reading The Earwig's Tail I have finally been corrected. It turns out all the movies and all the people that told me about this were wrong. Cockroaches can't actually withstand large amounts of radiation. So if an atomic bomb did go off, they may actually die off with us, and there will be nothing at all left on this planet. Not even mutant cockroaches like we thought there would be.
According to MythBusters cockroaches would be able to survive a nuclear explosion. In an experiment they did, only ten percent of cockroaches died at the same radiation level of a nuclear bomb. They say this happens because of their simple body composition. But if the blast was ten times a normal nuclear bomb, they would die off. So this myth is true and false I guess. It would depend on how radioactive the bomb was to determine if the cockroaches could live. Hopefully we will never find out if this is true with an actual real world test. I'm not looking forward to that at all.
