Irradiated Soil is the scar a reactor accident leaves in the Ala Industrial mod: the blast tears the surface open, and fallout settles only on the cells the explosion actually destroyed — within 8 blocks of the epicentre and only on natural ground such as dirt, sand, gravel or stone. A plank or concrete floor never takes the contamination, and an intact reactor shell keeps every fallout cell inside. Irradiated Soil is not crafted from anything and no recipe uses it: the block is a consequence, not an ingredient.

Four visible contamination steps show how poisoned each cell still is: fresh fallout glows acid green with dense specks at full dose, the tint dulls towards brown as the steps drop, and step 0 no longer radiates. Every random tick (the game's own background check) gives each cell a 20% chance to fade one step, water resting on top doubles that chance to 40%, and step 0 eventually turns back into ordinary dirt — the crater keeps its shape, the poison leaves. Irradiated Soil follows the mod's common radiation rules: the dose falls off with the square of the distance and a solid wall blocks it completely, so walking past a scar is survivable while building inside without a shielding suit is not. A whole crater never sums up: the dose counts only the nearest cells and stops at a ceiling of eight blocks. Dug with a shovel or bare hands — hardness is just 0.6 — Irradiated Soil drops itself and keeps radiating from the inventory as strongly as a uranium ingot: one step below refined uranium and fuel rods. A shielding chest silences the emission entirely. Ala Industrial runs on Minecraft 26.2 Java Edition, on both Fabric and NeoForge.
