-- 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 metre 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
|

|
||||
-- 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) m, which is
|
||||
-- the maximum distance one can get from the node centre 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 the distance in metres from a node at which an
|
||||
-- unshielded player will be damaged by 0.25 HP/s. Or, equivalently, it
|
||||
-- is half the square root of the damage rate in HP/s that an unshielded
|
||||
-- player 1 m away will take.
|
||||
--
|
||||
-- Shielding is assessed by sampling every 0.25 m along the path
|
||||
-- from the source to the player, ignoring the source node itself.
|
||||
-- The summed radiation resistance values from the sampled nodes yield
|
||||
-- a measure of the total amount of radiation resistance on the path.
|
||||
-- As in reality, shielding causes exponential attenuation of radiation.
|
||||
-- However, the effect is scaled down relative to real life: each
|
||||
-- metre-point of shielding, corresponding to a real-life halving of
|
||||
-- radiation, reduces radiation by 0.01 nepers (a factor of about 1.01).
|
||||
-- This 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
|
