Jocelyn et at:

I cannot find the reference but I do have some information on them:

the machines operated at 50 kV - at 38 mA,
the tube was usually 7.5 inches (approx 20 cm) from the sole of the foot
and the dose was calculated to be approx 116 R for a 20 second exposure

will try to dig up the reference where I obtained these figures
