Technical Guidance

Here you will find data and articles on radiation shielding, frequently asked questions (FAQ), monitor performance, specific gamma ray constants, mathematical derivations, radiation protection widgets  - everything we have personally found useful from our own tool kit. New resources will be uploaded here from time to time.

    X-ray equipment: Constant potential 2-30 MV. A useful graph to calculate the dose rate output of a constant potential x-ray generator in Gy/h per mA at a distance of 1 m based on a tungsten target for one specific filter and varying MV. The text below the graph explains the conversion process to modern SI units.
