Characters in a radioactive environment must make a Vigor roll every hour spent in low radiation, and every minute in high radiation. Each failure results in a Fatigue level.

• Recovery: Fatigue from radiation fades at the rate of one level every 24 hours, or half that if the victim can shower or scrub away lingering dust and other contaminants.
• Incapacitation Effects: The victim contracts radiation sickness, a Long-Term Chronic, Minorly Debilitating disease, as explained under Disease.
