[RBE/absorbed dose relationship of d(50)-Be neutrons determine for early intestinal tolerance in mice].
RBE/absorbed dose realtionship of d(50)-Be neutrons (ref.: 60Co) was determined using intestinal tolerance in mice (LD50) after single and fractionated irradiation. RBE is 1.8 for a single fraction (about 1000 rad 60Co dose); it increases when decreasing dose and reaches the plateau value of 2.8 for a 60Co dose of about 200 rad. This RBE value is used for the clinical applications with the cyclotron "Cyclone" at Louvain-la-Neuve.
