Researchers have found that microscopic worms are currently living in the Chernobyl Exclusion Zone (CEZ), seemingly without any radiation damage. This tiny species has emerged as an unlikely survivor since the catastrophic nuclear accident that rendered Chernobyl uninhabitable. The colossal tragedy that took place in 1986 has turned CEZ and its surrounding area into the most radioactive landscape on the planet. Humans had to evacuate the area in the aftermath of the disaster, which left the place uninhabitable because of the high levels of radiation that still persist 38 years later. Some reports say that humans won’t be able to live in the area for at least another 20,000 years. But microscopic worms appear to be able to reside in the same ghost town with no qualms.

The research team collected nearly 300 wild nematode isolates from various areas within the exclusion zone around Chernobyl, each with differing levels of radioactivity.

While it’s surprising to see some kind of life thriving in the radioactive zone, it does not mean that Chernobyl is safe, Sophia Tintori, a postdoctoral associate in the Department of Biology at NYU, said. “It more likely means that nematodes are really resilient animals and can withstand extreme conditions. We also don’t know how long each of the worms we collected was in the Zone, so we can’t be sure exactly what level of exposure each worm and its ancestors received over the past four decades,” Sophia said.
The finding does not suggest that Chernobyl is safe. It could mean that these worms are a lot more resilient than other species

Did the sudden environmental shift select for species, or even individuals within a species, that are naturally more resistant to ionizing radiation?” she said.
