I'm using an ion chamber (Ludlum9) to measure x-ray
scatter. The beam is only on for 2 secs, and the meter response time
(to 90% final reading) is about 3 secs. So, I'm reading low, but how
low? Does anyone have a plot of response vs. time? Are we looking at
a hysteresis curve here? I figure I can calculate a correction factor for
my survey, from such a plot.
