Source Calibration and Dose Rate Data

Date Initial Source Strength (Ci) Current Source Strength (Ci) Distance to Faceplate (cm) Exposure Rate (Roentgen/hr)°
6/27/17 20 9.3 30.5 17.691
9/11/17 20 9.3 30.5 17.606

°Calculated by TSO using [math]\dot x = \frac {\Gamma A }{ D^2} [/math] where [math]\boldsymbol{\Gamma} = 3.3 \frac {(cm^2)(R)}{(mCi)(hr)} [/math] , [math]\mathbf{A} = 9.3 Ci [/math] , [math]\mathbf{D}=(\text{Distance to faceplate} + 11.2cm) [/math]

Total dose calculated by [math]\int\limits_{t_0}^{t_f}\dot x\ dt [/math]
