E0A01 What, if any, are the differences between the radiation produced by radioactive materials and the electromagnetic energy radiated by an antenna? A. There is no significant difference between the two types of radiation B. Only radiation produced by radioactivity can injure human beings C. RF radiation does not have sufficient energy to break apart atoms and molecules; radiation from radioactive sources does D. Radiation from an antenna will damage unexposed photographic film, ordinary radio...
