Radiation and hazard settings

Registry: hbm:radiation_config. Files: data/hbm/hbm/radiation_config/<group>.json. See Game settings for loading, replacement and validation.

radiation

diffusivity, half_life_seconds, fog_rad, fog_chance and world_rad_effects apply to dimensions that omit them in their dimension radiation settings.

Field	Meaning and default	Range
`cleanup_dead_dirt`	Dead Grass reverts to dirt on random ticks; otherwise only under a dark, light-blocking cover; default `false`.
`diffusivity`	Radiation-field diffusion rate; default `10`.	[0.000001, \texttt{f64::MAX}]
`enable_chunk_rads`	Enables the radiation field: emission, spread, decay, fog and block decay; default `true`.
`enable_contamination`	Enables entity radiation: accumulation, dose and effects; default `true`.
`enable_contamination_on_ground`	A landed `hbm:contaminating` item emits into the radiation field and disappears; default `true`.
`fog_chance`	Each field region above `fog_rad` spawns radiation fog with chance 1 in this value per second; default `20`.	[1, \texttt{f64::MAX}]
`fog_rad`	Field radiation above which radiation fog can spawn; default `100`.	[0, \texttt{f64::MAX}]
`half_life_seconds`	Radiation-field decay half-life in seconds; default `120`.	[0.000001, \texttt{f64::MAX}]
`neutron_activation`	Players carrying radioactive items gain neutron radiation, and player exposure above `neutron_activation_threshold` neutron-activates inventory items; default `false`.
`neutron_activation_threshold`	Player radiation exposure in RAD/s, after protection, above which inventory items activate; default `15`.	[0, \texttt{i32::MAX}]
`world_rad_effects`until NTM 1.0.1Applies to NTM 1.0.0.Shown because All revisions is selected.	Radiation decays surface blocks where the field is at least 5; default `true`. `false` also stops this decay in dimensions whose settings set `world_rad_effects` to `true`.
`world_rad_effects`since NTM 1.0.1Applies to NTM 1.0.1, 1.0.2, 1.0.3, 1.0.4.Shown because All revisions is selected.	Radiation decays surface blocks where the field is at least 5; default `true`.

hazards

The disable_* keys switch off item hazard types. Soot, heavy-metal and poison values are pollution levels at the affected position.

Field	Meaning and default	Range
`buff_mob_threshold`	Soot above which naturally spawned hostile mobs, except glyphids, get +100% maximum health and +150% attack damage; default `15`.	finite \texttt{f64}
`disable_asbestos`	Disables `hbm:asbestos` hazards and asbestos accumulation; default `false`.
`disable_blinding`	Disables `hbm:blinding` hazards; default `false`.
`disable_coal`	Disables `hbm:coal` hazards and black-lung accumulation; default `false`.
`disable_cold`	Disables `hbm:cold` hazards; default `false`.
`disable_explosive`	Disables `hbm:explosive` hazards; default `false`.
`disable_hot`	Disables `hbm:hot` hazards; default `false`.
`disable_hydro`	Disables `hbm:hydroactive` hazards; default `false`.
`disable_toxic`	Disables `hbm:toxic` hazards; default `false`.
`enable_lead_from_blocks`	Breaking a block where heavy metal is at least 5 gives Lead Poisoning without Particulates head protection; default `true`.
`enable_lead_poisoning`	Heavy metal above 25 at eye level gives Lead Poisoning without Particulates head protection; default `true`.
`enable_poison`	Poison above 10 at eye level gives Poison or Wither without Corrosive Fumes head protection; default `true`.
`enable_pollution`	Enables pollution: accumulation, spread, effects and destruction; default `true`.
`enable_soot_fog`	Soot fog on clients; default `true`.
`pollution_mult`	Multiplier for added pollution; `rampant_mode` turns exactly 1 into 3; default `1`.	[0, \texttt{f64::MAX}]
`soot_fog_divisor`	Soot fog scale d: with e the soot above `soot_fog_threshold`, fog colour blends by \min(e/d, 1) and fog distance is render distance / (1 + 5e/d); default `120`.	(0, \texttt{f64::MAX}]
`soot_fog_threshold`	Soot at which soot fog starts; `rampant_mode` multiplies it by the effective `pollution_mult`; default `35`.	finite \texttt{f64}
