WebAs an example, the weighting factor or RBE of plutonium-238 (238 Pu) is between 10 and 30; thus, the roentgen equivalent in humans (rem) is 10–30 roentgens in air (rad). Similarly, the dose equivalent following alpha emission is larger than the absorbed dose, which is confined to an immensely small area in human tissue because alpha irradiation travels only a short … WebWhat is RBE meaning in Medical? 20+ meanings of RBE abbreviation related to Medical: Vote. 16.

WebPurpose . In the current work, the RBE of a 212 Pb-conjugated anti-HER2/neu antibody construct has been evaluated, in vitro, by colony formation assay. The RBE was estimated by comparing two absorbed dose-survival curves: the first obtained from the conjugated 212 Pb experiments (test radiation), the second obtained by parallel experiments of single bolus …
