DefinitionA <MASS ENERGY TRANSFER COEFFICIENT> is a <Property> that is, for a beam of indirectly ionizing uncharged particles acting on the material, mu_tr/rho = (1/rho).(1/R).(dR_tr/dl) where dR_tr is the meA <ENERGY> that is transfered to kinetic <ENERGY>of charged particles by interactions of the incident radiation R in traversing a <DISTANCE> dl in the material of density rho
