= Cumulative alpha-decay event density
{title2=$D(t)=\int_0^tR(s)\,ds$}

The number of <alpha decay> events per material volume accumulated over time. For constant <alpha-decay event rate density> $R$, $D=Rt$; otherwise $D(t)=\int_0^t R(s)\,ds$. Multiplying by a damaged volume per event gives a dimensionless overlap parameter.
