Radioactivity
Radiation resistance represents the extent to which a material
attenuates radiation passing through it; i.e., how good a radiation
shield it is. This is identified per node type. For materials that
exist in real life, the radiation resistance value that this system
uses for a node type consisting of a solid cube of that material is the
(approximate) number of halvings of ionising radiation that is achieved
by a meter of the material in real life. This is approximately
proportional to density, which provides a good way to estimate it.
Homogeneous mixtures of materials have radiation resistance computed
by a simple weighted mean. Note that the amount of attenuation that
a material achieves in-game is not required to be (and is not) the
same as the attenuation achieved in real life.
Radiation resistance for a node type may be specified in the node
definition, under the key "radiation_resistance". As an interim
measure, until node definitions widely include this, this code
knows a bunch of values for particular node types in several mods,
and values for groups of node types. The node definition takes
precedence if it specifies a value. Nodes for which no value at
all is known are taken to provide no radiation resistance at all;
this is appropriate for the majority of node types. Only node types
consisting of a fairly homogeneous mass of material should report
non-zero radiation resistance; anything with non-uniform geometry
or complex internal structure should show no radiation resistance.
Fractional resistance values are permitted.
