Quantities associated with this Unit
Quantity: total linear stopping power
Concept definition: -dE/dχ, where -dE is the energy [ISO 80000-5:2007, item 5-20.1] decrement in the χ-direction along an elementary path with the length dχ [ISO 80000-3:2006, item 3-1.1].
 
Reference type: PR
Reference: [ISO 80000-10:2009, item 10-55.a]

Quantity: linear energy transfer
Concept definition: For ionizing charged particles, dEΔ/dl, where dEΔ is the mean energy lost in electronic collisions locally to matter along a small path through the matter, minus the sum of the kinetic energies of all the electrons released with energies in excess of Δ, and dl [ISO 80000-3:2006, item 3-1.1] is the length of that path.
1 J/m = 1 (m · kg)/s2.
