-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.

---[[
-Radioactive nodes cause damage to nearby players.  The damage
-effect depends on the intrinsic strength of the radiation source,
-the distance between the source and the player, and the shielding
-effect of the intervening material.  These determine a rate of damage;
-total damage caused is the integral of this over time.
-
-In the absence of effective shielding, for a specific source the
-damage rate varies realistically in inverse proportion to the square
-of the distance.  (Distance is measured to the player's abdomen,
-not to the nominal player position which corresponds to the foot.)
-However, if the player is inside a non-walkable (liquid or gaseous)
-radioactive node, the nominal distance could go to zero, yielding
-infinite damage.  In that case, the player's body is displacing the
-radioactive material, so the effective distance should remain non-zero.
-We therefore apply a lower distance bound of sqrt(0.75), which is
-the maximum distance one can get from the node center within the node.
-
-A radioactive node is identified by being in the "radioactive" group,
-and the group value signifies the strength of the radiation source.
-The group value is 1000 times the distance from a node at which
-an unshielded player will be damaged by 0.25 HP/s.  Or, equivalently,
-it is 2000 times the square root of the damage rate in HP/s that an
-unshielded player 1 node away will take.
-
-Shielding is assessed by adding the shielding values of all nodes
-between the source node and the player, ignoring the source node itself.
-As in reality, shielding causes exponential attenuation of radiation.
-However, the effect is scaled down relative to real life.  A node with
-radiation resistance value R yields attenuation of sqrt(R) * 0.1 nepers.
-(In real life it would be about R * 0.69 nepers, by the definition
-of the radiation resistance values.)  The sqrt part of this formula
-scales down the differences between shielding types, reflecting the
-game's simplification of making expensive materials such as gold
-readily available in cubes.  The multiplicative factor in the
-formula scales down the difference between shielded and unshielded
-safe distances, avoiding the latter becoming impractically large.
-
-Damage is processed at rates down to 0.25 HP/s, which in the absence of
-shielding is attained at the distance specified by the "radioactive"
-group value.  Computed damage rates below 0.25 HP/s result in no
-damage at all to the player.  This gives the player an opportunity
-to be safe, and limits the range at which source/player interactions
-need to be considered.
