Ion Chamber Dose Timing Specifications
Measuring time (pulse width)
The Auto-Dose mode Accu-Dose Advanced only provides a
pulse width (time) measurement capability when you use either
ion chambers or dose diodes.
For ion chambers, the 10X6-6 and 10X6-6M are recommended.
The range of pulse width extends from 10 ms to 9999s. The
uncertainty is 4 ms (or 50 ms for the 10X6-1800 only) plus 0.1%
of width.
The minimum dose rate for the 6cc Chamber is 650 mR/min or
95
μ Gy/s.
Minimum total dose for the 6cc Chamber is 0.54 mR or 4.7 μ Gy.
For other 10X6-series chambers, these minimums are inversely
proportional to chamber volume.
When using adapters for 10X5 or 10X9 chambers, time
measurements are valid for the -6 and -6M chambers only.
