Contamination Zone is a group of people who are united by our love for the Chernobyl Zone. We are a non-profit organisation and every year we raise thousands of euros for good causes in the Chernobyl Zone, such as firefighting equipment, monument restoration, animal welfare and more.
If you are planning or thinking about a trip to the zone, please check out our trips to Ukraine in 2023 and if you still have unanswered questions, feel free to get in touch!
