[ RadSafe ] Beta Correction Factor

[Redmond, Randy (RXQ)]

We do our beta correction factors at contact with U-238 and they are
typically 3.2 to 3.8.  Sr/Y-90 is done at ORNL at 30cm and is typically
1.1 to 1.3.

Looking for technical data on the Beta Correction Factor for:

1.  R.O. 20
2.  Contact Window Open
3.  Sr/Y-90

I have data for 30cm but could not find it for a contact reading.

Thanks
Dave
