The quotient of [math]dE[/math] by [math]dl[/math], where [math]dE[/math] is the mean energy lost by the charged particle due to electronic interactions in traversing a distance [math]dl[/math], thus:
[math] L = \frac{dE}{dl} [/math]
The unit of linear energy transfer is joule per metre J m-1, often given in keV μm-1.
See high linear energy transfer radiation and low linear energy transfer radiation.
