[math]D \equiv \lim_{_{_{ \! \!\! \! \! \! \! Δ m \rightarrow 0}}}{\frac{Δ \bar ε}{Δ m}}[/math]

"The absorbed dose is the quotient of the mean energy imparted [math]\bar ε[/math] to matter of mass [math]Δ m[/math], in the limit as the mass approaches zero."

"Here [math]\bar ε[/math] is the expected energy imparted to the medium averaged over all stochastic fluctuations"

Stochastic fluctuations -> (random processes)

[math] 1 rad = 100 \frac{ergs}{gram} = 0.01 Gy[/math]
