| | | 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. |
