# Exposure Rate from X-ray Equipment (Dose Rate)

The following resource provides the output (dose rate) of various x-ray tubes (and higher energy x-ray generators) at a given potential - presented originally in R/mA at a fixed distance from the target. We have included conversion factors to SI units where appropriate (i.e. mGy/h or Gy/h per mA at 1m). Use with caution! Wherever possible you should use the data that comes with a specific x-ray tube, or even better have the output dose rate measured. Use this resource for historical interest or as a sanity check / comparison for other data you may have. For a different approach to obtaining x-ray tube dose rate data, check out this resource: Calculate an estimate of x-ray dose rate from an x-ray tube given kV and mA. Alternatively, how about trying out our X-ray Tube Dose Rate Calculator.
