Linear Energy Transfer Calculator

Formula

The formula to calculate the Linear Energy Transfer (LET) is:

\[ LET = \frac{dE}{dx} \]

Where:

\( LET \) is the linear energy transfer.
\( dE \) is the energy loss of the charged particle due to electron collisions.
\( dx \) is the total distance traveled.

What is Linear Energy Transfer?

Linear Energy Transfer (LET) is a measure of the energy deposited by a charged particle per unit distance as it travels through a material. It is an important concept in radiation physics and helps in understanding the effects of radiation on matter.

Example Calculation

Consider an example where:

Energy Loss (dE): 5 MeV
Distance Traveled (dx): 2 mm

Using the formula to calculate the Linear Energy Transfer:

\[ LET = \frac{5}{2} = 2.5 \text{ MeV/mm} \]

This means that the linear energy transfer for this example is 2.5 MeV/mm.
