What is the LD50/60 radiation dose for cockroaches?

The LD50/60 radiation dose refers to the dose of radiation that is lethal to 50% of a population within 60 days. For cockroaches, this dose is approximately 10,000 rad. This high level of radiation tolerance is due to their robust biological mechanisms, which allow them to survive extreme conditions that would be fatal to many other organisms.

In contrast, other options represent doses that are either too low or not representative of the actual radiation tolerance levels observed in cockroaches. Understanding the LD50/60 for different species is crucial in fields like toxicology and radiation biology, as it helps to gauge the relative vulnerability of various organisms to radiation exposure.
