This document discusses the use of robots in radioactive environments like nuclear power plants. It describes how robots can perform dangerous tasks in places with high radiation that would be unsafe for humans. The document outlines the basic components of robots, the types used such as ROSA and IRV, and their applications for maintenance, inspection, and retrieval tasks. In conclusion, the use of robots for work in radioactive areas allows humans to be protected from radiation exposure while important jobs can still be completed.
