Radiated

Your character is suffering from a significant amount of Radiation poisoning. The more radiation, the deadlier the effect.

More information

You can get radiated not only by visiting the wrong place (like Glow) but also for being hit by some of the wastelands creatures (like Alien). Higher doses of radition can affect your SPECIALs, and lower for example your Strength and Agility. After receiving a large amount of radiation your character dies.

Radiation resistance reduces the amount of radiation your character is being exposed to. Rad-X can improve radiation resistance.
Radiation can be cured with RadAway or intervention of a doctor in one of the cities.
