"the war is even more traumatic than chernobyl," says mayor yuri fomichov. as russian forces slaughter civilians en masse and show either a recklessness or a readiness to risk a disaster like chernobyl happening again, they've targeted nuclear facilities with tanks and repeatedly launched low-altitude missiles directly over nuclear reactors. that is one of the most terrifying things i've ever seen in my life. petro kotkin oversees alm of ukraine's nuclear facilities. he says the kremlin knows it's playing with fire, but the soldiers on the ground don't. take chernobyl, which russian forces captured for a month. so they were digging in radioactive material? radioactive material? >> they wer >> they were digging in radioactive soil. >> reporter: so have the soldiers now been poisoned? >> yes, they are poisoned. >> reporter: does that make you smile?
