How strong is the vitality of cockroaches?

Cockroaches have a strong vitality, and they can survive by cutting off two tentacles.

The tenacious vitality of cockroaches:

According to the ecological habits of cockroaches, a biologist once came to a conclusion: if there is a global nuclear war on the earth one day, all creatures in the affected area, including humans and even fish, will disappear, and only cockroaches will continue their lives!

This is because under normal circumstances, the radiation that the human body can bear is 5 rem, and once the total radiation exceeds 800 rem, it will die.

Blattella germanica can tolerate 9000~ 105000rems, and Periplaneta americana can tolerate 967500rems(rems stands for radiation dose). Rem dose equivalent? Rem [Walter] (SV)1SV =100 rem) so that cockroaches can survive even if there is a nuclear explosion.

A cockroach with its head decapitated can live for 9 days, and the cause of death after 9 days is starvation.
