SUMMARY
Linear Energy Transfer (LET) for electrons is defined as the ratio of energy deposited (dE) in a medium to the incremental distance (dl) traversed by the particle. In the context of electrons, dl refers to the average energy loss per unit length along the full path of the particle. LET varies with the energy of the electrons, and it is crucial to consider the average LET when discussing real radiation beams, as electrons interact strongly with the medium, leading to rapid energy loss and the production of secondary electrons.
