Which compares the problems associated with radioactive waste created from generating electricity using fusion reactions to waste created from generating electricity using fission reactions? the radioactive waste from fusion reactions becomes less hazardous much sooner than the waste from fission reactions. the radioactive waste from fission reactions becomes less hazardous much sooner than the waste from fusion reactions. although their radioactive wastes are hazardous for the same period of time, fusion reactions produce less waste than fission reactions. although their radioactive wastes are hazardous for the same period of time, fission reactions produce less waste than fusion reactions.
