The radiation shielding suit (shortened to radiation suit in the manuals) is an item that appears as a white hazard suit. Picking one up will make players immune to damaging floors for 60 seconds and fill their vision with a green haze. When 5 seconds remain, the green haze will begin blinking, signaling the end of the suit's effects. The suit has no armor value and does not protect the player from monster attacks in any way. Picking up one radiation suit while another is still in effect does not shield the player for an additional 60 seconds, but merely resets the protection time to 60 seconds (for instance, in E3M7: Limbo, the player may inadvertently run into additional radiation suits while navigating the blood tunnels).
