[[High linear transfer radiation]]: Radiation with capacity, by its own or by the secondary radiations it generates, of linear energy transfer higher than around 10 keV μm<sup>-1</sup>. Normally high LET radiation is assumed to include protons, neutrons and alpha particles (or other particles of similar or greater mass) except for protons having energies greater than around 4 MeV.

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.
