For ionizing charged particles, \(L_\Delta = \frac{dE_\Delta}{dl}\), where \(dE_\Delta\) is the mean energy lost in elctronic collisions locally to matter along a small path through the matter, minus the sum of the kinetic energies of all the electrons released with kinetic energies in excess of \(\Delta\), and \(dl\) is the length of that path.

\(L_\Delta\)

\(L_\bigtriangleup\)

"Linear Energy Transfer" (LET) is the linear density of energy lost by a charged ionizing particle travelling through matter.Typically, this measure is used to quantify the effects of ionizing radiation on biological specimens or electronic devices.
