This article is about the Radiation Suit. If this is not what you are looking for, see Dive Suit (Disambiguation).


For your convenience the radiation suit has been added to your blueprint database.

The status of the Aurora's crew, and the ship's long-range comm relay, is indeterminate. Exploring the crash site may provide further information.

The Radiation Suit is a piece of Equipment which prevents player damage from Radiation. The blueprint is unlocked automatically after the Aurora has exploded.

It consists of three parts: the Radiation Suit itself, the Radiation Gloves, and the Radiation Helmet. These three parts are all added to the Inventory when the player crafts the Radiation Suit in the Fabricator. 

The Radiation Suit parts must each be placed in their respective slots of the Paperdoll UI to take effect. When not worn, all pieces of the suit take up four inventory slots (2×2) each.


The Radiation Suit is the only way to survive inside the radiation zone after the Aurora's explosion. Therefore, it's very important to get a Radiation Suit as soon as possible.

The player can swap out parts of the Radiation Suit for other items, such as the Rebreather. However, to eliminate radiation damage completely, the player must equip all three parts. Equipping other parts thus results in partially blocking radiation damage in exchange for whatever bonus the other equipment gives.

The Radiation Suit is no longer needed after the player repairs all the breaches in the Aurora's drive core room.
