volumetric Sources¶
volumetric sources emit particles from randomly sampled starting positions from within the radioactive volume of a given component.
This source type has been designed for Brachytherapy applications (though there may be other applications as well).
Specify source type as:
s:So/MySource/Type = "Volumetric"
And then add an additional required parameter:
s:So/*/ActiveMaterial
to specify which material within the given component should be considered radioactive.
So, for example, if you have:
s:So/Example/Type = “Volumetric” s:So/Example/Component = “ActiveSource” sc:So/Example/ActiveMaterial = “G4_Ir”
particles will start from randomly sampled positions within the Iridium parts of the component named ActiveSource.
See the new example: examples/Basic/VolumetricSource.txt
The energies and species of the emitted particles can be specified using the same parameters available to the Beam Sources.
