A medical researcher wishes to compare the tissue damageproduced by slow neutrons, which have a relative biologicaleffectiveness (RBE) of 2.2, to that produced by fast neutrons withan RBE of 8.8. For the slow neutrons, the absorbed dose is 560 rd. What absorbed dose (in rd) of fast neutrons will produce […]
