Source Calibration Data

According to the TSO calibration paperwork from 6/27/17, at 30.5cm, the exposure rate of the 20Ci source is 17.691 R/hr. The source strength on this date was 9.3Ci.



Date Initial Source Strength (Ci) Source Strength Distance to Source Exposure Rate
6/27/17 1 5660 30cm 11
9/8/17 1 5660 30cm 11
9/26/17 2 4500 30cm 11
9/26/17 2 4500 30cm 11



Date Run Number Run Time (s) Distance to Source Number of OSLs in Stack
9/8/17 1 5660 30cm 11
9/8/17 1 5660 30cm 11
9/26/17 2 4500 30cm 11
9/26/17 2 4500 30cm 11


According to the TSO calibration paperwork from 6/27/17, at 30.5cm, the exposure rate of the 20Ci source is 17.691 R/hr. The source strength on this date was 9.3Ci.



Calibration paperwork update to 9/11/17, at 30.5cm, the exposure rate of the 20Ci source is 17.606 R/hr. The source strength on this date was 9.3Ci.
