Radiation damage is another damage type like fire, cold, acid, etc. For each die of radiation damage you take you must make a save vs poison. Upon failure you gain a point of radiation sickness. Radiation sickness goes from levels 1 to 5. For each point of radiation sickness you take a -1 to all your attributes. Each point of radiation sickness is cumulative. When you reach level 5 you are at -5 to all your attributes and you must make a save vs poison 1/day or die. If you go beyond level 5 you die.
Radiation sickness goes away at 1 point per week. If a delayed poison spell is cast it cuts the time in half. A casting of neutralize poison removes 1 level of radiation sickness. A restoration spell removes all levels of radiation sickness.
Another option is at each level of radiation sickness you might develop another symptom like hair loss, brain cell damage, sloughing of skin, etc. For each level you roll a 1d6 and each level of radiation sickness increases your odds of getting an additional symptom. For example level 2 radiation sickness you might gain additional symptom on a roll 1-2 on a d6. Level 5 radiation sickness you develop one on roll 1-5 on a d6. Some of the symptom are flavor elements, while other might have mechanical penalty to them.
