[ RadSafe ] Portable xray units for industrial radiography

[Dahlskog, Leif]

We have measurements of a number of units using a MDH ion chamber.

 XIT 250 kVp 5 mA unit;
 5.45 R/min at 1m.  HVL 0f 7.55 mm Al.

Rigaku 250EGS2 250 kVp 5 mA;  
1214 R/min at 300 mm with 2mm Al filter removed.
With 2 mm Al filter in place 12.66 R/min at 1 m.

Sorry have no data on the more modern units such as the GE Eresco 300 kVp constant potential units but output could be considerably more.

Does anyone out there have an idea of what the range of output is for these sort of devices? I'm interested in knowing about how many R/min @ 1 meter could be expected from commercially available models.  I've seen some that spec out at 5 R/min at 1 meter.  Are there models (portable) with higher outputs?
