RE: Exposure Rate Formula for X-ray Machine

["Redmond, Randy R. (RXQ) " <RXQ@y12.doe.gov>]

The use is industrial.  I did not provide enough information in the original
question.  I am interested in a formula or formulas for estimating the
exposure rate in R/hour or R/minute at a specified distance from an X-ray
machine that uses the following variables:  kV, mA, tube to point of
interest distance, thickness and type of material making up the tube/filter.

Thanks,
