-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.

-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.

+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.

+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 the distance from a node at which an unshielded
+player will be damaged by 1 HP/s. Or, equivalently, it is the square
+root of the damage rate in HP/s that an unshielded player one 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 0.2 HP/s, which in the absence of
+shielding is attained at the distance specified by the "radioactive"
+group value. Computed damage rates below 0.2 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.
