    Volume Source

    With respect to Radiation Protection, a volume source describes a source of Ionising Radiation which can physically be represented by a solid space. For example a drum containing radioactive waste can be considered a volume source. Sources of ionising radiation are often represented in this way when calculations of estimates of exposures from the source are required. In many cases the volume source will only represent an approximation of the real source, but this is usually adequate if sufficient factors of safety are built into the model. Other useful descriptions of sources include the Point Source, the Planar Source, and the Line Source.

This revolution, the information revolution, is a revolution of free energy as well, but another kind: free intellectual energy.
