Irradiated Zones are areas with dangerously high levels of radiation. They are marked with the icon on the map.
Irradiated Zones are very dangerous. Players entering the affected areas without adequate protective gear are exposed to high levels of gas radiation. A fully unprotected player without any radiation resistance bonuses will receive a 1% increase to their Radiation Status bars per second.
An Irradiated Zone is characterised by the presence of dead trees and grass, which also form a visual representation of the boundaries of the high radiation area. Ionizing radiation hazard signs are placed along roads that lead into Irradiated Zones.
