Handbook of Radiological Protection

Please find here a wealth of Health Physics data from the classic UK publication 'Handbook of Radiological Protection'. This information is provided under the PSI licence C2006010311 obtained from HMSO. The publication from 1971 is presented here for historical interest so use with great care. That said, much of the data present is equally valid today as it was decades ago.

It is true that more recent publications are probably more refined, but this should not detract from the value provided by this resource.

    X-ray equipment: Pulsating potential 5-50 KV. A useful graph to calculate the dose rate output of a pulsating potential x-ray tube in mGy/h per mA at a distance of 1 m based on a tungsten target for different levels of tube filtration and kV. The text below the graph explains the conversion process to modern SI units.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.
