&deg;Calculated by TSO using <math>\dot R = \frac {\Gamma A }{ D^2} </math> where <math>\boldsymbol{\Gamma} = 3.3 \frac {(cm^2)(R)}{(mCi)(hr)} = .35 \frac {(m^2)(R)}{(Ci)(hr)} </math> ,  <math>\mathbf{A} = 9.3 Ci </math> ,  <math>\mathbf{D}=(\text{Distance to faceplate} + 11.2cm) </math>

There is an adjustment distance of 11.2cm which accounts for the distance from the faceplate to the <math> ^{137}Cs</math> source

Total exposures are calculated by <math>\int\limits_{t_0}^{t_f}\dot R\ dt </math>
