How does radiation work in Rust?

Each monument radiation zone has a dose in rads a second. The radiation protection of everything you wear adds up and comes off that dose. The game counts 50% protection at most. Clothing does not stop the radiation that builds up before the Deep Sea closes.

Where is the strongest radiation in Rust?

Missile Silo, at 80 rads a second with nothing on. The game counts 50% protection at most, so 30 rads a second always get through there.

How much radiation protection do you need?

A Minimal zone needs 2%, a Low zone 10% and a Medium zone 25%. High zones (51 and 80 rads a second) are stronger than the 50% the game counts, so some always gets through.

Rust Radiation: Every Zone and What to Wear

How radiation works

Dose: Each monument radiation zone has a dose: the rads a second you take at its centre with nothing on. A monument can have several zones, and the strongest one sets what you need.
Protection: In a monument zone, the radiation protection of everything you wear adds up and comes off the dose. The game counts 50% at most, so a zone above 50 rads a second always lets some through.
Taking it off: Pills, rad removal teas, medkits and some food take radiation off what you have taken in. What takes radiation off lists each one.
Deep Sea: Over the last 5 minutes before the Deep Sea closes, radiation builds up across all of it, Ghost Ship, Tropical Island and Floating City included. Clothing does not stop it.
