In Fallout Shelter, How Fast Does Radiation Heal without RadAway

By Daniel Rodriguez

I had a bit of a water issue, and now my 141 inhabitants all have significant radiation poisoning. Let's say they were at 50% poisoned ... how long would it take to fix? Is there any technique to speed it (e.g. uplevel my RadAway Production Room)?

1 Answer

Once there is sufficient purified water, radiation poisoning will decrease for dwellers in the vault under normal conditions. 50% radiation poisoning will go away in... about 4 to 6 hours. This cannot be sped up, only supplemented with the use of RadAways.
