A packet of anti-radiation drugs has a weight of 0.1 kg and neutralizes all the radiation accumulated in the body. It's five times lighter than vodka, but also much more expensive. It's unlikely to be found on the bodies of rookie stalkers. In Clear Sky, it only neutralizes 1/2 of the radiation bar.
Hints for fighting radiation
- If you need to go to an infested area for a short duration (like less than 30 seconds - you don't need more time to clear a stash), just go there and ignore the radiation and dropping health. When you're done, go to a safe area and take ONE anti-rad or an adequate amount of vodka. If needed, use some food, bandages or vodka to heal your wounds. If you have the time to wait for the level of radiation to drop, leave it; there's no need to waste medical supplies.
- If you have limited supplies of anti-rads or vodka, use an anti-radiation artifact, get into the area, get out and watch the radiation (slowly) clear out of your body; use medical supplies or food only if your health drops low.
- Or better yet, make permanent use of an anti-rad artifact and a health-restoring artifact, to alleviate the dangers of hazardous levels of radiation.
