View source for Lineal energy

The quotient of <math>ε_i</math> by  <math>\bar{l}</math>, where <math>ε_i</math> is the energy imparted to the matter in a given volume by a single energy-deposition event <math>i</math>, and <math>\bar{l}</math> is the mean chord length of that volume, thus:
<div style='text-align: center;'>
<math>
y=\frac{ε_i}{\bar{l}}
</math>
</div>
The SI unit of lineal energy is joule per metre (J m<sup>-1</sup>), often given in KeV μm,<sup>-1</sup> ([[ICRP Publication 123]], 2013)
