Block sources and emission rates.

  "targets": "minecraft:stone",
  "rate": {"type": "fixed", "emission": 0.005, "saturation": 1.0}
}
FieldMeaning and default
targetsBlock ID, block tag, or ID list receiving the source rule.
stateOptionalVanilla state-property predicate; defaults to every state of each target.
rateEmission model selected by its type.

The shipped absorber uses negative emission with zero saturation.

item_hazard derives an emission of raw_item_radiation * 0.1 / 20 and a saturation equal to the raw item radiation.

Express a state-dependent rate with separate state-filtered rules.
