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.

For formal radiation safety advice, see our Radiation Protection Adviser (RPA) services page.

    X-ray equipment: Constant potential 0.5-3 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 different levels of tube filtration and varying MV. The text below the graph explains the conversion process to modern SI units.

    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.

The definition of 'safe' is not strictly an engineering term; it's a societal term. Does it mean absolutely no loss of life? Does it mean absolutely no contamination with radiation? What exactly does 'safe' mean?
