Understanding Neutron Radiography Post Exam Reading VIII-Part 2a of 2A

Linear Energy Transfer [LET]
LET is the amount of energy transferred to the local environment in the form
of ionizations and excitations. Thus, LET indicates the potential for
biologically important damage from radiation.
Linear Energy Transfer can be thought of in two ways:
• an average energy for a given path length traveled or
• an average path length for a given deposited energy.
The standard unit of measure is keV/um.
