Determine how many nuclei are in the beam

Reference no: EM13304724

A beam of nuclei is used for cancer therapy. Each nucleus has an energy of 181 MeV, and the relative biological effectiveness (RBE) of this type of radiation is 16. The beam is directed onto a 0.210-kg tumor, which receives a biologically equivalent dose of 249 rem. How many nuclei are in the beam?
