In 1986, a nuclear reactor exploded at the Chernobyl power plant in Ukraine. It released deadly radiation and over 100,000 people had to leave the city.
The area around the power plant is still dangerous and people are not allowed to go there. It’s called the Chernobyl Exclusion Zone (CEZ).
Although everyone left, animals like wolves and horses still live there. Dr. Cara Love, a scientist from Princeton University, has been studying these wolves.
In 2014, Dr. Love and her team went to the CEZ. They put special radio collars on the wolves to track where they go and how much radiation they are exposed to. They also checked the wolves’ blood to see how it reacts to the radiation.
The wolves are exposed to a lot of radiation every day, more than six times the safe limit for humans. But they seem to be okay. Their immune systems have changed in a way that’s similar to humans who get treatment for cancer. Dr. Love also found that the wolves’ genes have changed to protect them from cancer.
This could help scientists understand how to protect humans from cancer. For example, some humans have a gene that makes them more likely to get breast or ovarian cancer. But Dr. Love’s work is trying to find genes that can help people survive cancer.
Because of COVID-19 and the war in Ukraine, Dr. Love and her team haven’t been able to go back to the CEZ. They hope to return when it’s safe.
