Dose Rate for X-ray Generator

Hi all,
University of Glasgow is issue a calculation of Dose Rate for X-ray Generator as below:
X-rays produced by the bremstrahlung effect. Dose rate is dependent on:
• Z, Target material (atomic number)
• V, Applied tube voltage (kV)
• I, Tube current (mA)
• d, distance from the source (mm)
• Filtration?

Rule of thumb formula: (with 1 mm Be filter)
D = 670 ZVI/d2 mGy/s

Does any one have differ calculation?

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
