This indicated the biggest factor affecting wildlife wasn’t nuclear contamination, as he’d expected, but human presence. A large area around Chernobyl was evacuated and is uninhabitable for thousands of years. Even 30 years later – 25 years after the country that built it ceased to exist – the full damage of that day is still argued. And yet, a community of about 200 people live there -- almost all of them elderly women. The town of Pripyat, once home to over 50,000 people, was abandoned, along with the surrounding farms and villages.

In a 2005 estimate, the World Health Organization theorized that 2,200 people who worked on the emergency response and recovery (of the more than 200,000 people participating) would die from radiation-related causes, such as thyroid cancer. His TEDx talk and TED Book are based on his After Chernobyl documentary project. Beasley and his team have also measured high levels in wolves, which they’ve caught and tagged with GPS collars and devices that track radioactivity. Open Translation Project.

Most animals, such as wild boar, Japanese macaques and marten, were more abundant in the contaminated zones where humans were excluded. The researchers plugged numbers and locations on the four most plentiful species (gray wolf, raccoon dog, red fox and Eurasian boar) into a statistical model which factored in type of habitat, distance to water, and distance to the edge of the zone (a way of measuring human presence). While camera traps don’t permit them to estimate population numbers, they did allow the team to investigate how radiation was affecting where the animals were found. Boars are especially radioactive because they eat tubers, grubs and roots in the soil, where Cesium-137 has settled. Meanwhile, wolves were 7 times more abundant in the exclusion zone than in control reserves in Belarus, and 19 times more abundant than in an uncontaminated reserve in Russia. I'm Ukrainian.
