Source Calibration and Dose Rate Data

Date Initial Source Strength (Ci) Current Source Strength (Ci) Distance to Source (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]

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