Q: A beam of nuclei is used for cancer therapy. Each nucleus has an energy of 183 MeV, and the relative biological effectiveness (RBE) of this type of radiation is 16. The beam is directed onto a 0.220-kg tumor, which receives a biologically equivalent dose of 153 rem.
A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid, which runs through steam turbines. These either drive a ship's propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. So
